Do you know his name?

So the business of making friends took a back seat today as I had my first day at my new job as a waitress at this deli in town. In the long run I see this venture turning into a friend machine with all the new people I'll be meeting. I just need to figure out how to charm these people into liking me.

Mainly the job of waitressing seems to be about busting your ass and socializing- and there are two types of socializing. Socializing to make conversation which ultimately results in friends, and socializing to get good tips.

I had a couple of encounters today where I felt my overall socializing skills could be fine tuned.

For example here is a little diddy I had between an elderly couple (this is legit verbatim):
me: How are you guys doing today?
old man: We are doing good by the grace of God.
me: Awesome, can I start you guys off with some drinks?
old man: Are you blessed by God?
me: Uh, well ya, sure. I have been pretty lucky in life so far.
old man: Luck and God are two different things. Do you know his name?
me: Um, uh... excuse me?
old man: Do you know his name?
me: His name?
old man: His name.
me: Um, God. Unless there is some other name that I don't know about.
old man: Jesus, his name is Jesus.
me: Oh right, Jesus, the lords son. So... uh, what would you two like to drink?

Now clearly, I need to brush up on my Jesus knowledge around these parts or else I just wont be able to make good conversation- no one wants to be friends with someone who doesn't even know his name.
