That's why I started out by saying it's a nice perk.

What I objected to was that it sounded more like "instead of grocery shopping after work, now you can stay at work longer" whereas "we will do the tiresome parts of life for you so you have more free time outside the office" is what I want.

The very few errands I can't do outside of working hours can't be outsourced: going to the dentist, etc.
