Hi, I work in DKH sainsburys (please no one kill me) on the tills sometimes. im just replying to say about the till cleaning we have to do it ourselves so sometimes its hard especially when where busy but we do clean the belts as often as we can, i sometimes keep a mosit j-cloth at my till to clean off sticky bits if it happens. but its beyond our control really, we do it when we can and as for food thats been 'chucked' near the belts...etc and sometimes drops onto your shopping thats also not 100% our fault, we have a small area for people to give it to us and they dont. ive had someone literally abandon a basket full of food on the end of my till (im not saying go put it all back, but just hand it to me, im not going to force you to buy it) the other stuff is obvisuly unacceptable.
