I don’t think that’s true the bills are rebound they don’t use stacks of new money each time they refill it, however whatever checks they use to ensure it’s real money is enough to catch 99% of all counterfeits and if not it’s going to be good enough that you and whoever you give it to won’t notice.
I can’t immediately they have a sense of awkwardness at all when it comes to each other they just never had the chance to learn it, it’s not like walking in on someone in the shower and suddenly you see something you have never seen before it’s more like the taste of your own mouth you taste it every day so you don’t notice it, the way a partner reacts is probably more interesting.
