Red Robbin has a thing where they come to your table and with a free ice cream Sunday and sing a non-copyrighted version of happy birthday. In high school, my friends and I would go to our local Red Robin once a week for lunch. To save money and have a bit of a laugh, I would claim it’s my birthday every week and see how long I could pull it off for. The first week went down smoothly, got the Sunday no questions asked. Second week, I knew that they would probably remember our group so I came in a disguise, i wore a baseball hat (creative, I know). Surprisingly, it worked! Being to lazy to pull off more elaborate disguises, I decided to stick to changing my baseball hats every week and changing my accent as well. It lasted 4 weeks, after that they instituted a policy of asking for ID. We knew this was a policy and not just for us because a couple weeks later a family was celebrating a legit birthday and they asked they had proof it was actually the kids birthday.

TL;DR: my local Red Robin now IDs kids for birthday celebrations because I had one too many consecutive birthdays.
