As pointed out elsewhere maybe the sales guy should know how to operate the thing he is selling?
Also, it sounds like a power cycle cleared up the issue so no big problems.

I don't know that a power cycle cleared the issue up, a reset definitely didn't. OP just said the salesperson power-cycled it, not that that fixed it.
I agree, why not have an technical guy there who knows how to operate the thing and can support the sales guy? If the company is sending only sales guys with no in-depth technical knowledge to a trade show, it's fully understandable and well-deserved if this sort of thing happens.

If I am buying an expensive piece of hardware you better believe I will ask questions about the intricacies and if I don't get answers I will not be buying.
