Do restaurant servers really have to smile constantly for customers?

I smile at EVERYONE, no other server does this. I flash a cute smile when I see someone.
but today, I was walking to the kitchen busy in the rush, trying remeber everything in my head, and no server is walking by with a huge smile on face, everyone is serious and they just smile when they serve the table. I’m not serving tables yet as I’m new, and one old senior already gossiped of me. How im so serious and then told other server im so serious. Later wen rush is over i smile as they r staring at me with an unlikeable face and then the son says there r u go Smile, MORE MORE MOREEE!!! MORE!!!

When im at a restraunt NO fucking server is walking by smiling. They r racing so busy. 🙁

even at fine dining restraunts no server is smiling. The dining area I work at is supposedly fine dining but it’s all kid servers teens and I’m not a teen but look like I’m 18 and not.
