I'm still holding onto , not sure for How long though, clearing own McD trays and thanking waiters/waitresses and minibus drivers etc.
However, very often I find myself telling off secondary school kids leaving their trays on table. And the not long ago, I gave a lecture to the principal of my son's kindy about why today's kids were growing up as entitled pricks.literally no one at the school paid attention to stair walking etiquette and just barged into you from all corners. As a result, she got signs( arrows pointing up and down) pasted on the floor. I ain't bothered about losing face or making too many friends. If i am right, no matter the only one, I will stand my ground.
