I was having dinner yesterday and I suddenly get a message from someone from another team.

Them: Hi
Me: Hi

(No response for 20 mins)

Them: I'm having some problem with your service. Its not working when I do <task>
Me: Okay, let me look into that.
Them: Also, <task2> is not working
Them: And <task3> has problems
Them: Could you also look into <task4>?
Me: (visibly sweating) Let's discuss this in detail in the morning.

[Next day, morning]
*convinced that the service has a major bug*
Me: Yeah, show me what is causing the problem.

They show me what they tried. Turns out they made an invalid call and got an error, AS THEY SHOULD, and reported that as a bug. And all the other tasks were because the first call didn't work.
