"Should I Have Asked That?"

I rang up a man in a wheelchair. He paid with a credit card and as I handed him the slip to sign, I worried that he might not be able to reach the counter to sign it. I asked him if he needed a clipboard to sign his slip. He said he didn't.

I suddenly worried that I had offended him and asked, "Should I have asked that?"

To my relief, he assured me that it was fine. In fact, he said he preferred to be asked that question than people who leave him hanging with no hard surface to use.
