The parking lot we were booted in did not have adequate signage denoting it was a paid lot. We drove around the perimeter of the lot upon arrival (after 12:30 a.m.) and did not see any signs. However, when we returned to our car and it was booted. The staff member, Frank, was incredibly rude and aggressive towards my best friend's boyfriend -- to point of potential physicality -- and when we explained that we had arrived after 12:30 (which was when he said Advanced Booting Services stops booting cars), he taunted us, saying we had no way to prove our arrival time, and then clamped a second boot on our car that we would have to pay to have removed!

Advanced Booting Services: your tactics are dirty and dishonest. We would have had no problem paying for the (first) boot had there been signs in the lot that we blatantly ignored. Your company needs more congenial employees and much better signage (or signage at all!).
