Senoufou, I DO find the younger US (smarmy) helpfulness patronising as soon as drive-thru workers see the gray hair that goes with my perky, order-placing voice-- but yes, I will take that senior discount thankyouverymuch.

OTOH, I don't find hands-on help patronizing at all, such as the small army of millennials breaking down my women's march table and carrying it and bags of gear to my car, as I sat on the running board answering other younguns' spontaneous questions.

That thing I described upthread about misread stuff-- in your post I read one bit as "ILL-trained...." ;-)
