Presumably, there's a lock on the door - they're not going to allow passers-by to enter - "Oops, sorry - just browsing."
So you could enter as a singleton. The benefit of two bowls, all to yourself, is that, if you fill the first bowl, you have a fall-back bowl on the other side. Perhaps some of the athletes are on special diets.
Or you could enter as a doubleton, with your special one. Nice big room, privacy, maybe - I dunno.
