When you ask your co-worker to get something from someone’s house where that someone’s sister will meet him to give your co-worker that something, and your co-worker tells you to phone the sister and tell her to meet him at the house any time before 3PM so you tell her to meet your co-worker at 2:30PM and your co-worker gets mad at you cause it’s way too close to 3PM which is the end of his shift, and then you have to spell it out to him that if 2:30PM isn’t a good time for him he shouldn’t hae told you to tell her a time any time before 3PM.
