Well, this post inspired me to cancel my order and either use another service or stop at the grocery with 3 kids, and my in laws waiting in the car. I will not support this guy in his business if this is how he treats customers.
You sound ridiculous Brian. I am not comfortable with a person like you handling groceries for my family. (I'm sure I'm the one who is out of line now so I guess everyone can flame away). If you are going to sit and argue with a customer who paid extra for groceries just for your service to deliver them within a specific time frame, (which you did not do) you are not going to get my business or the business from anyone I know.
Good luck to you and may you have fun working on those "customer service skills" we Disney people expect when we are there on vacation.
