You're digging yourself into a very weird hypothetical hole just to keep your very bizarre point alive.
You must have a very low tolerance for weird, if you think mentioning vodka and pot cookies is 'very weird'.
Out of the information we know about this situation: Girl blew up over a possible 4 5ths of a Cookie. A single cookie regardless of whether it was vegan or not, she blew up over a cookie that should cost no more than £1. If money is so important and rare for her to have, she shouldn't be spending it on a COOKIE!
You know in my previous post I agreed that if it's just a normal cookie, then yeah, it's a bit more crazy.
