I didn't really take note of this until after having dinner out with some friends from the Netherlands, but every single time my husband and I go to a restaurant, they sing some form of a happy birthday song to someone.  Of course they can't sing the actual "Happy Birthday" song due to licensing issues so each restaurant has its own annoying version.  Every time we are in a restaurant!

We have heard Spanish, Italian, Middle Eastern (La Shish) and even Korean versions.  They each seem to have their own brand of embarrassment to go along like putting on a big hat, making you stand up in front of everyone or some such silliness.  They always sing loudly, badly and usually have some sort of loud clapping to accompany said singing.

My children hate it and always have.  Even as babies they would start crying when someone started clapping and singing.  I'm starting to relate to their sentiment.  Enough already!
