Don't complain on a first date.
Oh my gosh, this is disgusting. Waiter, waiter, excuse me. Take this away. Ugh, I'm so tired from work. This week has been terrible. There has been so much to do and my boss is driving me crazy. Did I tell you about my sink leak? I hate my apartment so much. The stupid landlord won't fix anything. It's awful. Ow, these shoes are pinching my toes. Ugh, they are so uncomfortable.
Instead, find pleasant aspects of the evening to discuss and make sure and find a thoughtful compliment for your date's appearance.
Remember: No one likes whine with their cheese.
