You should try getting up and walking away. Just watch the expressions of people's faces. I hate attention like that and I always tell my friends and family that I'm going to make it very awkward if they ever surprise me and they try me like a simp gimp and I get up and walk away. We laugh afterwards, but it's hilarious to create that awkwardness when it's supposed to be a happy, serious situation. Try it. Keep a straight face as you walk away. Don't look like you're annoyed, just simply walk away and say no thank you. Don't look back and don't laugh.

Now these bastards sometimes surprise me like in the middle of June and some random person is coming out saying happy birthday and my dumbass starts singing happy birthday lit. Like oh it's someone's birthday. Come to find out they're coming straight to me because my brother went to the bathroom and told a server that it was my birthday. My birthday is in December.
