This reminds me of working at a citrus growers plantation in Cyprus...they're very down to earth, even a little rough round the edges (drinking scotch at the works dinner table


)...
So, they have a water dispenser just inside the offices. 10 feet away is a toilet, and it's not pretty

They're not averse to leaving (or using) a used cup by the dispenser, it gets confusing which is which.
I went to the loo one day, and one of the empty cups was on the windowsill.
Ever since, i had a vision of one of them drinking in the toilet, then putting the cup back by the dispenser.... it's a dilemma whether to even have a drink, even when you really want one
