If she knows where all the HVAC vents are, then she can direct particular people to sites that are warmer or cooler depending on their needs.
My daughter entered the workforce at the best possible time, it seems… Only a few months ago she turned 16, got a car, and suddenly was able to find a task in the food service industry. They made her a hostess, and paid her minimum wage plus tips, however for a first task, it was not so bad. She easily adapted to the work environment remarkably suddenly. It didn’t take long before she outgrew the site, and moved to a better restaurant and that’s when the real money started flowing in. One of the tricks she managed to learn was to check the different zones of the temperature control system to find any temperature differences. If she knows where all the HVAC vents are, then she can direct particular people to sites that are warmer or cooler depending on their needs. The bunch of us have a lot of old folks in our area, so she managed to figure out that resting them right under an air conditioning device vent was rarely a fantastic option because of how easily they got cold. On the other hand, younger people coming in for lunch didn’t prefer too much heating so she would seat them far away from the windows, which were the warmest area in the kitchen. Of course it works both ways, so when there are repeat customers who are rude or don’t tip well, she will basically place them in a temperature zone where they will be the most miserable! She is kind of salty at times, however I legitimately prefer how she is using the Heating and A/C device for her own purposes.
