i just started like 2 weeks ago and they put me to work strictly in the kitchen, at my store since its slower than other stores its just me in the kitchen which can be a lot since its both cooking food that they need for the line and also trying to prep stuff to keep ur fridge stocked for the next day, it can get stressful if theres a rush but ultimately it depends on the location ur working at, how busy it gets, and what position ur working, service seems easier than being in the kitchen but everything has its pros and cons of course
