I completely support the defensive adoption of a sardonic butler-persona for everybody on the other side of a cash-register. :p
"Why should I have to change? He's the one who sucks!"
Yoshihiro or Yoshiyuki would likely be called Yoshi by their friends.
Nobody made fun of my name particularly, it's not like anyone famous, I just don't like it very much. I don't call myself by my name in my head, or on the internet. For most of my life my friends and coworkers had nicknames for me and I prefered that. I associate my name with official paperwork, formal situations, negative situations, aquaintances, and salespeople.
Perhaps because of this I have a bit of fixation on names (people, places, and products) and judging them to sound good or bad. Some names sound great or fine and it's no surprise to me if 'Robert' likes his name and likes hearing it. But I struggle to imagine that people called 'Helpless' or 'Abuse-not'[1] thinking those are the most beautiful sound in the world.

I do think Dale Carnegie overemphasizes the importance of saying people's names, and in fact saying people's names in conversation often sounds forced and manipulative, but maybe that's just a cultural shift over the past century.
But, yeah, it usually sets off my spidey sense when somebody keeps using my first name in conversation. It's just seems weirdly unnecessary, so it makes me wonder why they're doing it.
Doc Rivers is an awesome name though.
