The bathroom is locked so that only paying customers may use it. All you need to do is ask a member of staff for the key or to unlock it. And there are people asking for money while you eat because of unfortunate circumstances. The staff do their best to be keep that at bay but sometimes compassion and hope win out and sometimes you get asked for money in a public place. Sorry you seem to have had an unpleasant experience! Hopefully the rest of your day went well.
There are poor people here
