The other day I was hanging out with a few friends and we ended talking about how I speak to cashiers, service attendants, etc by their name on their tag. This is apparently not a normal thing to do, even though I end up getting favourable service most times.
"Why would you do that? Just get your stuff, pay and go. They're just doing their job", it was said.
Having worked in retail back in my younger days, I understand how that might seem, but in my opinion, we're given (or chose) a name to make us an individual and growing up that helps shape us in a sense. And after a long day of serving customers who often just gets down to business, it's nice to be acknowledged by name in a positive way.
In improv, naming is an important act as well. By naming a character, object, or action it defines for everyone what or who it is. This first action can then lead on to establish the relationship status, emotional ties, etc. It also helps tie the scene together more so than having nameless characters and objects - the scene wouldn't be able to sustain itself for too long, I bet.
Same with life. If you call someone by name, you get their attention - you essentially establish the initial relationship. Whether it's just a one off transaction at the checkout, on a speed date or in business transaction, creating that 'bond' will get 'buy in' more effectively.
