I've had exactly 1 birthday circle (also with cake) done in my honour in my Salsa life. My good friend organized it unbeknownst to me, so it wasn't about popularity as I don't advertise my birthday.
At that time, however, I was a regular at Salsa parties and making efforts to get to know people, plus the DJ was also a good friend of mine, so it wasn't like I was some random person walking into the club demanding birthday funsies.
So at that moment, it felt kind of natural to have all of that boil over during that moment, especially after all the time I'd spend helping to build that community.
Was it nice? Yes. Was it necessary? No, it was not.
Did I feel like the world stopped turning for me during those 5 minutes? Honestly not really, because there were other things going on and others who didn't participate in the birthday circle were doing their own thing elsewhere.
It is a memory I will cherish because it was done in good faith.
But I get it, if you're not participating in it, it can seem like a waste of your 5 minutes.
Normally, I avoid them if I don't know the person. Sitting out for 5 minutes isn't going to kill me. I have more important things to complain about. If it happened every week, then that would be different. But even so, at any event, I need to take a break.
I consider any Bachata set more of a nuissance and a disruption to my Salsa night than a Birthday circle.
