Now whilst I understand the nature of not sticking the same finger in the cake mix twice as ' double dipping' I am confused by a sign on the wall on the place where I got my legs waxed last week. It said 'No Double Dipping' in a rather large A4 laminated sign. Now just to make it clear, the lady (not great English) uses an electronic sort of appliance which heats the wax inside itself before then dragging it over my leg then the usual ripping off manually. No dipping of anything required, no smearing of wax via spatula or whatever. I checked that there is no normally smearing wax...so what is double dipping?! I might venture out and ask next time but she is so lovely and so smiley that I think I may baffle and embarrass her with the question. Any ideas?
