Me: hey I have a major issue I need to discuss. Would you be free tomorrow at any of these times: A, B or C?

Him: Yes

Me: ... ... ... ok I’ve a new issue I need to discuss with you right now!

Yes

Well, he' s clear: he can be free at any of the three times

@mngr its funny I used to think that. No he’s not. In his mind he said yes to only one of the options and I now have to guess which one

I can see two possible solution:
1) break the question in three parts, hoping to receive one yes and two no as answers

2) break him until he understand

@mngr yes

Correct answer:

"Great, I'll see you at (whatever one of those 3 times you prefer.)"

If he comes back saying he can't do that time, ask him what specific time he was replying "yes" to. He'll probably be somewhat embarassed at that point.

@practiseSafeHex reply with 400 and wait 😋

@Commodore 418 for the win, but he'll flip on that one too because he wanted coffee instead.

RE: Sorry, I could not parse your answer correctly, please reply with one of the given options: A, B, C

You only asked if any of those times is ok, not which time is. You should ask which time is ok, if any.

This reminds me of interview we were taking recently. He answered with a firm yes for everything.

Me: Could you please give us an example for x?

Guy: "yes"

*Awkward silence for 5 minutes*

@fckIE that's a good strategy when you have no clue

@electrineer We initially thought he was nervous and did believe he knew something. We gave up when he couldn't answer what FTP is.

if (freeAt($A) || freeAt($B) || freeAt($C)) {
echo "yes";
} else {
echo "no";
}
// I suppose yes is a valid answer if they are free at one or more of the times

This sounds like a Monty Hall problem hidden in disguise

@electrineer and @stacked are onto something here.
