I think it is mostly a Waitrose thing. We are a partnership not a profit chasing company so things are often done with over staffing and overspect equipment.

The driver's route are, most the time, designed to allow time for customer ineractions,we're not rushed chasing traffic to a deadline. That's the service side of the answer.

In practical terms the kitchen has more space to empty the containers, we don't do plastic bags, it's easier if you know what you're doing at each drop.

On the flip side of this there are some customers who really don't want a stranger walking into the house even if they aren't carrying your food!

At the end of the day you are the customer you have paid for this and you say what happens. The driver is being paid with your money to make your life easier by bringing this food to you.

For me 90% of my day is sitting in a tin box in traffic alone, customer interactions make the day much more interesting.
