Sounds like this is more of a convenient excuse rather than an actual deal breaker.
Like there was likely something else going on and The vibes weren't there and this is a quick and easy way to get out of the relationship when you know it's not going anywhere.
And I feel relatively confident in this assumption because everyone knows that if a girl is really into you she'll put up with some really fucking weird shit to keep the relationship alive.
I am not a woman, but if I was with someone and they were like let's scam McDonald's for the shittiest chicken ever, I'd be like hey Mexican places are cheap let's go there. Or more likely just fuck off.
Especially on a first date. If you had pitched this as a fun "hacking" activity, then I can see the appeal, but if you're just doing this out of the blue, it comes off as scammy, cheap, and a waste of time.
