As far as my experience with uWink goes, I've never seen anyone have so many problems in a single visit. I've been there around 15-20 times total, usually with large groups, and its never been that bad.
It's true, occasionally you'll experience some hiccups, but I've never seen this many in one visit.
I'm willing to bet that most people here aren't familiar with Sheetz considering it is primarily a Pennsylvania thing. Sheetz is famous in the area for having really decent food, orderable through little kiosks at every store.
They pretty well own their niche at least in the area I'm familiar with. They're a good example of a business entering a saturated market (gas stations) but doing it better than everyone else to the point that most people that I know will go out of their way to go to a Sheetz rather than any other gas station.
Typically, they have their gas just a little below the average in the area, surcharge free ATMs, the Made-To-Order kiosks (sometimes located at the gas pumps), clean bathrooms, and a bit of a more friendly atmosphere than other gas stations.
They're actually a rather good example for startups.
There's a uWink coming soon to downtown Mountain View (corner of Castro and California where they old ranch house used to be). I just hope it isn't too gimmicky.
i've been hearing about uwink for years now. i thought it was originally a little terminal thing they installed at bars and restaurants where you could play against others across the country, but i could be wrong.
it's too bad the implementation seems to suck. i would have expected more from nolan bushnell, given his track record with atari.
I have eaten at uWink over a dozen times now over the past 10 months and I have never had any trouble with their ordering system, service, or credit card/check processing.
You, too, can own a slice of fail!
