Tipping on a carry out order??

[anonamoose]

I don't get the guy who tips for for sit down, but stiffs take out, what exactly do you tip for, because someone brought the food to your table?
Same time went into cooking it, taking your (special) order, ringing it up, preparing it, then all the cleaning.
Tip take out, about 1/2 of what you tip sit down service.

We're talking about someone dealing with you for 30 seconds vs an hour to sometimes two and you think it's just them bringing food to your table?

Tip someone half what you tip sit down service for 1/100th of the time spent on you?
