Yes, we assume that all vases need cleaning when they come back, that's factored into the price, what I'm getting at is when tealight holders come back stuffed full of fag ends where people have used them as ashtrays, and recently we've had our bay trees back with the pots full of fag ends and chewing gum. In those instances they require additional cleaning over and above the routine so I just wondered if anyone charged for that.
