The fact that I have to tip is my big complaint with my local food delivery service. I'm already paying at least $6 for the delivery, possibly an added 20% of the check if it's not a "partner" restaurant yet I'm still expected to tip. They go so far as to say the whole "fee isn't a tip, so make sure to tip" like the chain pizza joints do. I really don't see why tipping is a thing when I'm explicitly paying for the service. I'm sure the owner is just using the cultural institution of tipping to avoid having to pay his employees.
