Sir/Ma'am in Banking

Sir yes sir works fine.

Sir and ma'am are fine, Mr./Ms. are fine. If they ask you to call them Jack or Sally or whatever, do that.

haha poster above is joking. if it makes you feel more comfortable, you can say sir/maam once, then go directly to first name. it is perfectly acceptable to go directly to first name right off the bat though

I interned with a kid who used to call everyone Sir. It used to annoy the heck out of the senior guys. Just call them by their first name.

I am in the south and i still use my manners... the people i work with in NYC always laugh about it

Let me clarify, I use sir/ma'am or Mr./Ms. generally on meeting someone. 99% of the time people will say, oh, please call me (insert first name here).

Generally just call the person whatever they say their name is.

Yankees typically don't like it or find it amusing. I can't shake the habit, nor do I want to...especially ma'am. If they become regular coworkers it's one thing but first, second, third meetings will remain sir and ma'am.

Thanks for the input.
