Yes, I've always thought this too. I do this trick with the towels, and have in the past used a key or something else in my pocket to 'hook' the door open if the handle looks particularly disgusting. Still not 100% hygenic, but better than that door handle!
One local pie shop that I went to on occasions had a member of staff that not only used bare hands with the food, but also used to pet any customer's dog that came in with them, then went back to serving the customers again without going anywhere near the sink.
Consequently, I stopped buying stuff from there........
Yeeeeeetch.......:sqerr:
