Re: On an important first date what would you do?
It doesn't matter what you decide to do really. If you do buy it and talk about how she's beautiful blabla, everythings cool.
If you don't get her the flower and explain later how you don't think those people should kinda force guys into buying 'useless' stuff, because they put you in an uncomfortable situation, everything should be cool as well.
If the girl is gonna dislike you over one of these two choices, she's not as great as you think she is.
