What do you think about "small talk"?

I work at a job where I see about 30 customers per day for about 5 – 10 minutes each. Most of the time the only type of conversation we have is “small talk”, like how the weather is or how their day has been. It usually starts with “How are you doing?”, but the only thing is I don’t really care how they are doing because in 5 minutes I will never see this person again. I know its polite and its certainly part of my job to keep this customer happy so I just nod and smile like I really care about what they are saying.

Do you like to “small talk”?
