I hope she at least refused to put them anywhere other than the floor in front of her.
I learned a lesson from my little brother on this one.
After getting lousy service at a bar, my brother commented to the bartender that he certainly expected better. The barkeep responded “So, what are you going to do about it” and proceeded to show us who was boss.
My brother ordered a tap beer, then ‘accidentally’ knocked it to the tile floor, breaking the glass mug, and pouring beer across the bar, several stools and the floor. “Ooops, Sorry, didn’t mean to do that” was all he said, and we left. The barkeep got to spend the next bit of time picking up broken glass and mopping the floor, stools and bar.
I think the point was made, even though it cost him $1.25.
Sometimes businesses give stupid people the ability to make poor decisions. That doesn’t mean that the customer has to take the stupidity without recourse.
