He reminds me of a line someone said to me once when he was explaining why a new computer system wasn’t working right ....”you know those (computer) salesmen ... always sitting on the edge of the bed and telling you how good it’s gonna be ...” Ugh.
I was looking at new dishwashers once, I asked the very young salesman a simple question on something about the machine (I pretty well knew the answer), but as I was looking him square in the eye, he started babbling STUFF.lol
Finally I stopped him and said "Your making all that up, right, you really don't have an idea what it does?" He nodded his head, yes. rofl. Didn't buy from him.
