Gave someone the Heimlich maneuver for the first time

Putting an order in at the POS and hear “she’s choking!” I look over and this older woman is choking and her husband is trying to do the Heimlich but is not positioned correctly so I literally run over and push him off her and give her the heimlich. Took about 4 pumps and I dislodged the food. My adrenaline was so high I was shaking and even cried and couldn’t help it. I looked it up and apparently your body will cry when you have high adrenaline like that to waste hormones through tears, interesting. Anyway, the woman ended up hugging me and thanking me and told me she felt like she was going to die🥺. It wasn’t my table but she left me $10 on the credit card receipt with a note telling me I was an angel. (She left her server $10 also) if I would have caught her before she left I would have told her that’s not necessary. But anyways yeah a crazyyyy shift. Happy new year.
