Question for the people that go out to BF by yourself: What do you do if you need to go to the restroom while waiting in line, if you ask the stranger standing next to you in line to hold your place, aren't you worried that they may steal your place when you return or lie to you and say that they don't remember promising to hold your place? What suggestions do you have if you have an emergency while waiting in line? Has anybody brought one of those "portable restroom" with them and used them? Isn't it embarrasing to use those?
