Pros
As far as training goes, they jump you in pretty quickly but I never felt unprepared. My management was pretty lax as long as all the work was done, so it wasn't a stressful situation most of the time (except when it was really busy, when it kicked in high gear) and coworkers could have a lot of fun together if they wanted to. It's not exactly a dream job, but it's cleaner and less stressful than most fast food jobs, and the drive through is actually pretty fun.
Cons
The salary sucks. Raises are rarely given out, and when they are, they're incremental. Closers can get stuck with a lot of cleaning and general hassle that no one else wanted to deal with. Still, they're supposed to have all their work done and be out of there when their hours dictate. They're almost always understaffed. They overestimate what one person can do in their shift when they're alone.
