We get Tesco groceries delivered. Never had an issue until a couple weeks ago. I'm an ESL teacher and I work from home. I was teaching a class until 1:55pm and my Tesco delivery slot was from 2-3pm. Five minutes still gave me time, and last time I checked 2-3pm means 2-3pm. At 1:45pm, while I'm teaching, I hear the driver knock on our door several times. He's walking around the house, yelling my name "are you in??" Phone rings, can't answer. Keep in mind, I'm still teaching while all this commotion is going on, and I'm trying not to appear distracted. We can NEVER, ever leave the classroom unless it's a genuine emergency, like I became violently ill or something. I can't do anything until 1:55.
Finally the class ends and I'm expecting that the delivery driver has left. Luckily he stuck around. You bet I made it known to him that he was 15 minutes early, and that I couldn't answer the door as I was teaching until 1:55. He mumbled an apology. I get being 5 minutes early, but 15?? That's a lot.
