Cheers, rdanberry, the retirement home, woodworker and possibly the brothel I can do. Perhaps I should have explained the problem? The main thing is that at the resolution I (deliberately) chose to do this at, some things won't be obvious. Unless the fishmonger is selling a shark... hey, yes, I can do that!.... but I mean, in general, the "trade" has to be rather large. I doubt I can manage even stark nekkid ladies for a brothel let alone frilly stockinged ones... hrm. The barber I could fall back on the traditional stripey bar but it'd have to be pretty big.
Basically anything much smaller than 1m in size - is "tricky". I don't mind this being "silly" - it is a cartoony drawing after all.
