As a young man, when I was out and about with huge parties and had very little cash, I would make sure to stay within my means and not run up a tab that would put me in an awkward situation.
Women (and many men, too) don't have this level of wherewithal /discernment, as time and time again, men have bailed them out of an embarrassing money situation.
I wish I had your level of savagery, but I tend to be very gentlemanly with my vocal denials, but the underlying/in-between energy from which it's delivered carries a very harsh BITCH PAY YOUR OWN SHIT AND STAY BROKE YOU BUMB BITCH.
I tend to insult those who wrong me like a Brit.
