The worst experience I ever experienced was at a fairly popular diner in my area about 10 years ago. I never particularly liked the food at this establishment (they serve FROZEN vegetables and insist they are fresh

) and there had been discrimination claims against them in the very recent past. Still I had ended up there, being out voted during a party meant we were going there because they had the best milkshakes (they really didn't :whistling

.
Anyway, this was the LAST time I was ever there and the last time my friends ever went there too.
This diner is a 24/7 establishment, we arrived at about 9 pm and were the only customers in at that time before the bar closing rush came and were seated by a really surly waitress. She obviously did NOT want to be there, in the slightest. She was stomping around, sighing, and after we were seated it took her 15 minutes to get back to us to get our drink order. By that time we had already decided exactly what we wanted and just gave her our full orders.
This completely undid her. She asked us this, I am not joking here; "Have any of you ever eaten out before? You are served DRINKS first, tell me your DRINK order."
At this point in time we finally noticed another waitress who was staring at our waitress moon-eyed from behind the bar. She slipped out into the kitchens and another woman whom I assume was the manager on duty stuck her head out an bellowed our waitress's name.
Surly waitress disappears.
We wait.
And wait...
... and wait.
At least 20 minutes pass, no one comes in to check on us, we have been there for long enough that we all are starving, half of my friends just want to ditch, the other half want to wait it out, I just want to go but right when we decide to finally leave the surly waitress comes back.
She had no apology, just went back into surly work mode and took our orders and fluttered back into the kitchen. Where the manager and other waitress were I have no idea. It was like everyone in the diner just disappeared into the kitchen and never came back out.
We wait 20 more minutes... no drinks, no food, no waitress. I want to leave as well as two others, the rest want to wait it out "She could be having a rough day!" (no kidding?) and once again am out voted.
We wait a little bit longer, stomach is trying to eat itself, no one else has come in to the diner, it's probably about 10:30 now, we should be LEAVING at this point when the waitress comes back with our orders.
Food is cold, milkshakes wrong flavors, I am pretty sure she spit in them, she also didn't serve us our drinks. She flees after setting down our food and just BOLTS out the front door.
That is the last time we see ANY staff.
We pick at our food, I don't even touch anything, one of my friends try flagging down someone by walking into the kitchens... they are empty.
No one else is around.
We finally left around 11, we did not pay for anything because no one gave us a bill. A couple other people came in and waited for a few minutes to be seated before they gave up and left after asking us if anyone was around.
Never got an explanation for that one.
