Meat Cutter? WTF...what happened to Butcher? Is that the PC term for "you are a butcher but damned if we will actually pay you that well"?
I worked in a Butcher shop in High School. High End local place that did have ties as part of our uniforms, under aprons of course, but I didn't interview with a tie and I don't think anyone else did either.
It is, or was, a good paying honest blue collar job. Smoke breaks out back, eating sandwiches made outa the goofs. LOL
I'd say wear good clothes, button shirt, no tie.
Tips:
Be yourself
and Good luck!
