To Tip or not to Tip

Recently had an experience that left me a bit pissed off.  We had gone to a nicer resturant that had served us well a couple of days before.  Note this is associated with work time, away from home.  We arrived and were fairly quickly seated and the drink order taken.  At that point things started slowing down.  It took some time to get the waiter back to place an order.  We got that in, the food arrived in a timely manner and it was ok, but not as good as the first time.  I wonder if returning so quickly had anything to do with the interest in the quality?  Anyway we put that down pretty quickly as we had been out all day and had traveled over 400 miles and spent 5 hours on a location where not much was happening.  Needless to say we all were not in a mood to piss off time waiting as we wanted to get to our rooms and shower and get to bed… but NOOOOOOOOO!   We got a bill hand written, which by the way when we got the final was incorrect, but they said the system was down and they couldn’t take the credit car or rather they could but had to take the number and turn it in later.  I do not like leaving a credit card deal when I didn’t sign for it.  They fumbled around and I agreed but figured I would just cash the deal with the copy of the receipt for expenses anyway and not use the credit card.  We waited and waited and every so often we figured the waiter was headed back but he would turn to another table… so we waited some more then they come back and say, the system if coming back up and they will have our bill in a little bit??? ok , that turned into another 20 minutes before we got the bill… in all total it took them 45 minutes from from the time I gave my credit card for payment until we actually got the bill to sign, but it was a computer generated bill so if they try to stick me I am going to raise HELL… as I now have a reciept that took and hour and a half to get.  But back to my point, in these cases, how much do you tip?  the service was ok for the meal but the after meal process was almost in-tolerable… – WD0AJG  ( I left them about 8%… half a tip)
