Imagine a situation when a group of friends is standing on a train station platform and waiting for a train to come. They all know that the train will arrive in about one or two minutes and will stop for only one minute, after which it will leave. One of the friends really needs to use the bathroom. What would be a common way he would ask his friends here about whether he can still make a trip to the bathroom before the train arrives?
Do you guys think I still have time to go to the bathroom?
or
Do you guys think I will have enough time to have a trip to the bathroom?
or what?
