I remember one time I had a package that was big, awkward and very heavy. I was thinking about how I was going to get it on my hand truck and to the door when the guy came out, stood at the top of his porch (steps involved) and said "need a hand with that?" I replied "yeah, that'd be great." He was fully expecting me to say no and waited for me to struggle getting it up the porch and to the door when he said "I couldn't find my shoes." I got a kind of envious/jealous vibe from him. Yeah, you can sometimes sense that from customers.
