There's no reason to take offense--You'd be part of the first group, through no fault of your own.

Although you could have obtained a gym membership and checked it out. Or just showed up and asked nicely to see the system in use. If you introduced your pelf as "someone who wants to make check-in systems easier," I bet you'd get some info.

I have had several experiences like this: I get asked to build software and hardware systems for trade shows, and I get to attend to implement the technology. What I learn during the first show rivals all the meetings and handed-down info from the stakeholders. I am actually very excited about my projects now that he second occurrence is coming up for some of them.

Getting a membership would have cost him money & hassle. Showing up at the client's place of business without permission from your company sounds like a good way to get reprimanded, maybe even fired if the company got the impression you were "going rogue" & trying to steal the contract from them.

My intention with my comment was to encourage people to avoid behaving helplessly. That is a potential trap that could keep one surrounded in mediocrity.

I did intend to suggest that an unapproved visit to your employer's client would be conducted anonymously, but I did not word it very well.
