Central Parking

I printed out a coupon to park here for a few hours. The coupon was $8 for "Any 6 Hours". I returned to my car at 5 Hours and 56 minutes and they told me that because it had not been 6 hours yet that I had to pay $4 extra. I told them that I would stand there for 4 minutes to get the $8 rate if need be and they gave it to me. When they pulled my car around, though, I went to get in and found a cigarette stubbed out on the back carpet!! With Fresh Ash!! I immediately went back inside, where I had to wait for the supervisor to finish a phone call on HIS CELL PHONE (?!) and then he came outside along with the attendant. I would've been perfectly fine with just getting back my $8 (I have an older car with no plans of re-sale) but they insisted on taking photographs and submitting a "claim" which the supervisor basically told me was all BS and I would never see any thing come of it. Will NEVER park here again. Staff is rude and obviously they think it is okay to smoke in someone else's car.
