Even though we are paying for everything ourselves and had a very small budget, we had planned on tipping our caterer, florist, and my hair/makeup stylist since most things I've read say that tipping vendors is expected. However, in the past week, our caterer has added an unexpected extra $400 (after we had already paid it off), and my hair/makeup stylist charged more for the trial than I was expecting. Both of these things put together have pretty much taken away any extra money that we have. Is it terrible if we don't tip vendors? The florist is already paid off and the other 2 will be given the final payment the day of the wedding.
