distractions?

i've mentioned that i work a part time job, but never where i work.
i'm still not going to say where i work, but i'll say what i do.
i'm a cashier.

being a cashier, you get to meet so many kinds of people.

well, one day this older guy comes to my register.

i tell him hello and ask how he's doing.
he says he's doing great.

then he asks, "there's a lot of pretty girls that come in, huh?"

i look at him and kind of smile and nod.

he smiles back and says, "you must get distracted, right? i mean, if i worked didn't work in an office, i'd have so many distractions looking at all the girls."

"i wouldn't know...i'm too busy looking at the guys," is what i wanted to say, hahahaha.
instead, i just smiled like i know what he's talking about and give a little shrug.
he goes on to say, "all i do is work in an office, i don't get to see much there. it's all the same people."

he was actually really nice and had great energy and a contagious smile. it turned out he was recently divorced and is a bachelor again. you could surely tell he was enjoying his "bachelorhood" and checking out all the ladies.

he seemed like a fun guy, it's just that he made me uncomfortable without knowing it.

i'm curious what i would have done if i was out though.
would i have done the same thing or would i actually have let him know i wasn't attracted to the girls?

part of me thinks, i wouldn't have said anything only because i didn't know him and he doesn't need to know my personal life.
hahaha.
i'm curious as to what any of you would have done in my place.
or for those that are out, have you had an experience like this
and if so, what did you do?
