My mother has the hots for the young waiter at her local Chinese resteraunt

She always likes going there with my Dad on Thursday nights, because she knows that's when the waiter has a shift. My dad doesn't even care. My dad was telling me that she gets giggly and nervous watching the young Chinese waiter, and usually ends up drunk at the end of the night. I think this waiter is getting sick of her. Should we be concerned? 😒
