missred

so i was checking my account activity online. thursday night i went out to ale house and ended up with a 131 dollar check some how...my drunk bff and her shot buying...but i wasnt gonna make her pay the whole thing so we split it down the middle. so like 65 and some change a piece. my brother was also there and i told him just buy ur food and ill get the rest and you can leave the tip. soooo i left 5 and some to round it off to an even number and brother left like 15. all together it rounded off to be 20 dollars which is 15% of the check. well im looking at my account and she didnt take the 5 and some i left for tip. im pretty sure she was like whoa...ok shitty tipper dont want your fucking money. it should be obvious tho bc my brothers check was less than what he tipped her and we all come in together...idk...maybe im giving her too much credit or thinking into this too much but i go there often and im not a shitty tipper but i wasnt ready for that ridiculous check....bff is never allowed to drunk order again. i still feel judged and i dont like it. ive been on her side of the table so i feel her but damn...
