Depends on the situation, I would play the wait and see card. Go ahead and ask them to call. Don't be afraid to say when the can check it ( eg. 3 hours later)

Depends on the situation, I would play the wait and see card. Go ahead and ask them to call. Don't be afraid to say when the can check it ( eg. 3 hours later). And check what the request is. If it's a bullshit interruption, than say you don't appreciated it for this. If it's a good question, don't worry. You will understand why they did it. In my case: totally fine, bit I never got an interruption for bullshit :)
