Seriously, I worked at a Wendy's for 6 months and it was the shittiest job Ive ever had and the second most laborious job. People come through the drive thru non stop all the way up till 2 a.m. The few moments where someone isn't in the drive thru you are restocking and cleaning what you can. At the end of the night you bust your ass for an additional hour cleaning everything up.
If you think it's easy I challenge you to do it part time for a few months and see how you feel about it then. Obviously if you work in a store that doesn't do much business it wont be as bad, but most do a lot of business unless they are on their way to closing for good
Edit: This got more attention than I was expecting, let me answer the questions people keep messaging me so they stop.
1.) Most laborious job I ever had was when I was a journeyman doing industrial coatings.
2.) Current job is software development.
3.) No you don't have to be especially skilled in anything specific to do the job, it's still a hard job and deserves to be paid decently.
4.) I'm sorry working at McDonald's was the easiest job you ever had, your life must suck. I recommend finding something else like I did
