Home Depot

I applied for a job as a cashier at home depot looking for experience interacting with customers and the job as a cashier in general. But the experience is terrible at this home depot at least. I haven't worked 2 months and Im having to do jobs not assigned to a "cashier". For example having to be a loader is ridiculous. Back and forth its exhausting and I honestly feel bad because customers cant usually load their items into the car and have to sadly struggle to load and get home
