no restrictions - I use what's available, but not with ease, I'd rather not do my business at friend's houses but when you gotta go...public toilets are OK too as long as there is not feces smeared on the walls and all that, I just can't wrap my head around how people treat public bathrooms, like how do you get that shameless to leave a mess like that? I would be in there half an hour cleaning up after myself if I ended up with feces all over the place
