McDonald's

I went to mcdonalds to get food for my disabled mother and when i came back they said that i had left the parking lot even though i hadnt and in that three minute span had hooked their tow truck to my car. they threatened to tow me if i didn't pay them a hundred dollars. they told me they saw me leave which never happened. they also said that they had towed 13 other people that day. they forced me to pay the hundred dollars and was extremely rude and threatening
