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...-- absterge, Apr 26 2008 These guys dominate the market for point-of-sale IT, http://www.micros.com/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.-- DrCurry, Apr 26 2008 buggar, I thought it was thumb but welcome back [absterge]-- po, Apr 26 2008 Sp.: bugger.-- MaxwellBuchanan, Apr 26 2008 <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>-- pertinax, Apr 27 2008 [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.-- absterge, Apr 28 2008 Alternative: Middle finger/no middle finger-- Noexit, Apr 28 2008 I initially read this as Thumb Fu, which I thought might be a sort of martial shiatsu.-- bungston, Apr 28 2008 random, halfbakery
