I really enjoyed working there. My coworkers were all very friendly and my work days went by in a flash because of it. Typically, I'd come in, count my till for my day at the register, serve customers quickly and with a smile and when not doing that, tidying up my own station and the general areas of the store.
My manager, while questionable in their attitude towards their employees, was always making sure that the customer left happy.
The hardest part of the job would have to be that some people just cannot be pleased. They expect the world out of you and on the busiest of days, it's just not possible to satisfy everyone. Through it all you have to be apologetic and humble.
The most enjoyable part would be that I truly enjoyed serving others who appreciate the convenience of a ready-made pizza and the quality of service from the staff.
