Thumb Thru   (+4)  [vote for, against]
A single satisfaction metric

Avast, ye bakers! I'm back!

At each drive-through, place a camera at the exit of the queue, aimed generally in the direction of the drivers' windows, and politely suggest that customers render either a thumbs-up or thumbs-down gesture in relation to their overall satisfaction with the experience as they breeze away. A simple bit of software should readily be able to sort out whether it was an up, down, or abstain/no-data vote.

Lots of garbage data to sift, lots of privacy laws to uphold, etc, but possibly useful data to mine. Highest satisfactions at times of day/week/month/year, intervals between measurements, etc.

Now that I think of it, maybe I'll code it myself and set up shop selling these to chains as a consultancy service...

These guys dominate the market for point-of-sale IT,
so you'll probably want some integration with their hardware and software. [pertinax, Apr 27 2008]

Why bother requiring drivers to gesture? Modern cameras can distinguish smiles.

<a word in your ear>[po] has a free pass on spelling 'bugger', just like her free pass on capitalisation, in recognition of her services to flirtation.</awiye>

[Dr], I was thinking about your question, and I think the appeal that I can see is the sense of empowerment. Raising a hand is taking action to make a definitive statement, vice the possibly passive facial expression.

Buggir, it's good to be back.

I initially read this as Thumb Fu, which I thought might be a sort of martial shiatsu.
