If it is a shoe shop, that definitely legal. I manage MY shop single-handed from 6a.m. in the morning till 10p.m. at night seven days a week (only open 6hours on Sunday but I use the rest of the time polishing shoes). I have been doing this for 45 years, and do I get a word of thanks - NO I DON`T. When I can fit them in I have to do all the repairs so I am cobbling a lot of the time. NO you perverts, cobbling not gobbling. And then my employer comes in seven times a day to have his shoes polished, AND he rests them on my knee when I do it!.
