I'm wondering mostly in the informal context of a chat room. Basically:
Person A: I just ordered a pizza!
Me: At what time is it getting delivered?
Me: At what time is it getting here?
Me: When would it get here?
Me: How soon is it getting delivered?
Mostly is that I don't want to sound like the non-native speaker who ends up writing a super long sentence for something that could have been said in a much simpler way.
