Not directly related, but I turned into One Of Those People who complain, decades ago, when visiting a business partner / supplier on behalf of my company. They had premises on a big building on an industrial estate a mile out of the nearest town. I drove 100 miles for a meeting there, arrived quarter of an hour early and was told to wait in reception for the relevant person to collect me and she would be "just a few minutes" as she was on a call.
Me: "No problem, may I just use your loo while I'm waiting?"
Receptionist: "I'm afraid not as you have to pass through security doors to get to it. When Ms X comes to collect you, she will show you where the loo is".
20 minutes passed, so the person I'm meeting is now late, and I'm getting increasingly uncomfortable with a full bladder.
Me: "Please can I just use the loo? I wouldn't ask if it wasn't urgent".
Receptionist (with patronising head tilt): "No, I'm sorry, that's our policy, she'll just be a few minutes so not long for you to wait" (tinkly laugh).
Then of course, when Ms X finally showed up, I had to awkwardly explain that she had to take me to the toilet before we could do anything else.
Driving 100 miles home I had time to get annoyed. If an adult asks twice to use the loo, anyone must realise it's urgent, surely? Wrote to the CEO and asked whether they felt this was welcoming or inclusive, as some people have conditions that mean they can't wait 20 minutes. Policy was changed.
