Some Houstonians have complained there are scam artists in downtown Houston taking advantage of those using privately owned parking lots. I have reveived an email from a woman who was victimized just last week. The woman says homeless people are pretending to be parking attendants and charging drivers $10 to park in the lots. The woman who paid the fee came back later to find her car booted by management at the lot because she did not put her money in the meter on the lot. The woman says she was among 11 other people who fell for the scam. Officials with Houston’s parking enforcement say they are aware of the scheme and drivers should pay close attention to the signs on the lots and follow the instructions.
