Not the best range of cars

First of all they didnt have the ford focus I asked for, the man informed me they only had one which wasnt in use at the moment and havent been in use for some time.I didnt feel comfortable driving the clio so I asked for it to be change the man cleaning the car had no problem with this however the man on the desk did and started arguing with his colleague right for front of me he was very aggressive and unprofessional and it was quite scary to be honest
