Valentine’s Day scam
Some restaurants will comp your meal on Valentine’s Day if you propose. It’s a super-nice gesture that, unfortunately, some sleazeballs take advantage of. The OP shared a story of how her friend and her husband would go from restaurant to restaurant and propose in the hopes of scoring a free meal. It worked last year, so they went to the same restaurant again the following year.
Unfortunately for them, one of the waiting staff was present during their faux proposal the previous year and promptly told the OP’s friend and loser husband to get out. They did indeed get out and made their way to another restaurant where they’d do the whole fake-proposal thing to get a free dinner.
