You work in a small very low-tech grocery store in a state which has a bottle and can deposit law (as in Michigan, California, Connecticut, Massachusetts, Maine, New York, Vermont, Hawaii, Iowa, or Oregon). One of your responsibilities is to count up cans and bottles and return people's deposits to them.
In practice, the deposit law serves mainly as a source of income for the homeless people of your state, who go through dumpsters and ditches looking for cans to return.
One day, a man who looks (and smells) homeless comes into the store with a large black garbage bag full of bottles and cans and wants the attendant deposits for these. When asked, he says he does not know how many there are in the bag, so you can't take his word for it. Most of the bag contains beer cans, some of which have been used for chewing tobacco (which has leaked out of the cans and gotten all over the outsides of everything, and the inside of the bag), and the whole bag is incredibly ripe-smelling because it has been out in the sun on a very hot summer day, while the homeless guy was walking it over to your store.
Your store is not obligated to take these, as they are for products you do not sell. Also, you would not have to take these even if they were from your store, because they are dirty and sticky and smelly and covered with tobacco spit, and you are legally allowed to refuse to take back anything that nobody in the store is willing to touch. Your co-workers have previously counseled you to refuse any such bottles and cans as the spirit moves you.
The homeless guy smells like alcohol already, and is presumably only collecting cans in order to get together enough money to buy more. However, if he's as alcoholic as he looks, he may well require the alcohol in order to function, and who are you to judge what he does with his body anyway; if he wants you to take his cans and give him money so he can get drunk again (or continue to be drunk, whatever), what business is it of yours?
There's nothing illegal about what he's asking you to do, and your store is probably the only one which would take them anyway -- other stores are more high-tech and have machines which collect the cans, but the cans in question have to be in fairly pristine condition, or at least not all crunched-up (as a quick glance into the bag reveals that most of the cans inside are). In other words, you are probably the guy's only shot at can redemption within walking distance.
But the cans smell really bad, and are coated with the germs of whoever drank out of them, and spat tobacco into them, and there are enough of them that it's going to mean a pretty substantial amount of time, if you take them.
A) accept the cans, smell the smells, enable the alcoholism, and incur the wrinkled noses of your co-workers, or
B) deny the cans, leaving the homeless guy fundless and possibly D.T.-ing, for no good reason beyond your own prissiness about not, literally, wanting to get your hands dirty?
