One of my cousins has worked there for about 6 months now. She said it’s very hard work. There is a lot of stuff that you have to memorize in a quick amount of time when you first start working there. The hours vary from day to day, week to week. Sometimes you have to stay late, if someone else is sick or doesn’t show up for some reason. Sometimes the customers are idiots and jerks. Sometimes her co-workers are idiots and jerks. The pay is low. She often comes home with aching feet and a sore back and a sore neck from doing repetitive work all day (or night) long. She says she can’t get the smell of grease out of her clothes. Because she has bills to pay, she has to go to work even when she is tired, or not feeling well. She says she’s really not thrilled with working there, but she is grateful that she has a job, and she gets up every day and goes in and gives it her best. She’s a nice girl with a nice personality. You have to at least pretend to be happy to be there and do your best work. If you don’t, there’s ten other people lined up to take that job.
Make sure you really want to go back to work, and are able to work, before you take a job if it’s offered to you.
Best of luck, friend.
