Those who work in a small establishment with fewer customers have to walk a shorter distance and burn fewer calories than those in busier larger bars and restaurants who have to walk farther and/or a faster-paced restaurant.
Also, if food runners serve to the table for you, you’ll burn fewer calories. If the kitchen is in the basement, and your tables are on the first floor, traveling up and down the stairs will increase your calorie burn hugely.
The figures are average but you can assume that anything that increases/decreases your effort will cause you to burn more/less Moving up/down a weight group (or even 2) may be more accurate for you. Only you can judge against the average.
