The smell of Marijuana coming from the shop was very strong. One of the employees was talking about taking the rental cars racing every weekend. The did not accept debit cards one week, when they had the previous week. When I showed up for my vehicle, they had sent it out with another customer and had to myself and my 3 kids in a much smaller vehicle and then charged me for the larger vehicle. Will not be returning.
