Comparable restaurant sales include the benefit of menu price increases of approximately 1.75% and 1.0%, implemented in April 2021 and October 2020, respectively. In addition, we implemented a menu price increase of 4.2% in October 2021.
In 2021 YTD, we opened 18 company restaurants, including four Bubba's 33 restaurants. As of September 28, 2021, an additional 15 restaurants were under construction. We currently plan to open 26 to 29 company restaurants across all concepts in 2021.
In 2022, we plan to open 25 to 30 Texas Roadhouse and Bubba’s 33 company restaurants. In total, we expect store week growth of 5% to 6% from 2021, excluding the impact of potential franchise acquisitions.
Other sales primarily represent the net impact of the amortization of third party gift card fees and gift card breakage income. The net impact was $2.1 million and ($1.6) million for Q3 2021 and Q3 2020, respectively, and ($5.6) million and ($6.3) million for 2021 YTD and 2020 YTD, respectively. The increase in both periods was primarily related to a favorable adjustment of $4.8 million recorded in Q3 2021. This adjustment primarily related to a shift in our historic redemption pattern which indicated that the percentage of gift cards sold that are not expected to be redeemed had shifted from 4.0% to 4.5%. As a result, we adjusted the breakage recognized for all gift cards that had not been fully amortized. The impact of this adjustment was offset by increased amortization of third party fees due to the increase in sales through our third party gift card program.
Franchise Royalties and Fees. Franchise royalties and fees increased by $1.4 million, or by 30.1%, in Q3 2021 compared to Q3 2020 and increased $5.2 million, or by 40.4% in 2021 YTD compared to 2020 YTD. The increase was due to higher average unit volumes, driven by comparable restaurant sales increases at domestic stores. Comparable restaurant sales at domestic franchise stores increased 33.5% and 38.5% in Q3 2021 and 2021 YTD, respectively.
We anticipate that our existing franchise partners will open as many as four restaurants, primarily international, in 2021, and as many as five restaurants in 2022.
Food and Beverage Costs. Food and beverage costs, as a percentage of restaurant and other sales, increased to 34.6% in Q3 2021 compared to 32.1% in Q3 2020 and increased to 33.1% in 2021 YTD compared to 32.9% in 2020 YTD. The increases were primarily due to commodity inflation partially offset by the benefit of a higher guest check. Commodity inflation was 13.9% and 7.4% for Q3 2021 and 2021 YTD, respectively, primarily driven by higher beef costs.
For 2021, we currently expect commodity cost inflation to be approximately 10% with prices locked for approximately 70% of our remaining forecasted costs and the remainder subject to floating market prices. For 2022, we currently expect commodity cost inflation in the high teens in the first half of the year with prices locked for approximately 30% of our forecasted costs and the remainder subject to floating market prices.
Restaurant Labor Expenses. Restaurant labor expenses, as a percentage of restaurant and other sales, decreased to 33.2% in Q3 2021 compared to 34.7% in Q3 2020 and decreased to 32.7% in 2021 YTD compared to 37.4% in 2020 YTD. The decrease was primarily due to an increase in average unit volumes as well as several items related to 2020 including labor inefficiencies as we converted to our hybrid operating model, relief payments and increased benefits provided to our hourly employees. In 2021, the benefit of a higher guest check amount also contributed to the decrease. These decreases were partially offset by higher wage rates primarily due to labor market pressures along with increases in state-mandated minimum and tipped wage rates, the impact of employee retention payroll tax credits in the prior year, and an increase in workers’ compensation expense.
In Q3 2021 and 2021 YTD, we incurred costs of $0.3 million and $3.7 million, respectively, for relief pay and enhanced benefits for our restaurant-level managers and hourly employees. This compared to $1.8 million and $17.2 million in Q3 2020 and 2020 YTD, respectively, for relief pay and enhanced benefits for our hourly employees.
In Q3 2020, we recognized employee retention payroll tax credits of $4.5 million related to the relief pay for our hourly employees that was paid during the first half of 2020. No employee retention payroll tax credits were recognized
