@NeroCat9999vr,
You're just as childish as bambam... yes, the manager gave them the ketchup but he wouldn't have if he knew what they were going to do with it. What they did was very stupid.
Second, regarding what people wear at McD's - they might have come from somewhere else where their clothing was appropriate. Are you saying they should have gone home to change into 'normal clothes' before grabbing a burger? That's the stupidest thing I ever heard of. Nobody expects to go anywhere and encounter a ketchup fight between two idiots. What do you mean, "you're not supposed to look nice for a fast-food restaurant."?? What a maroon.
You say you came here for answers, not to give them - well, you should stick to that!
And don't tell any of us to shut up because we're only giving her our opinions, which is what she asked for.
