Good for you, Über. That was going to be my advice to you.
Hopefully that taught them a lesson.
Fortunately I’ve never had to deal with a 7/11. If I go anywhere, its usually a McDs since the bathrooms are off to the side and the counter help usually has their hands full keeping up with customers food orders. Normally they’re open to anyone and you don’t need to ask for a key to use it.
7/11 clerks control access and its likely the only tiny little bit of power they have in this world and they take full advantage of it by being as dickish as possible :)
I bet the vision of that guy cleaning your throwup off the counter gives you a good chuckle every time you think about it. Congratulations on teaching him a lesson he won’t soon forget.
Score one for the good guys !!!
