Ya since Corey picked you up, he can now ask for smokes. If he doesnt ever send to you and disappears, trust me you will get picked up by others, maybe multiple others. Corey in the mean time will be shamed on.
Corey is a good dude though and has proved trustworthy like like everyone else that hangs out here.
It's always a nice jesture to attempt to get them out as soon as possible. If it won't be for a few days announce it like Corey has. Keep in mind people have real life obligations and something may come up and interfer with their ability to get smokes out to someone. So always give it some time or simply PM someone if you don't get it in a timely manner.
