Mother's Bike Shop

Went to buy a bicycle helmet and saw a doodle bug mini bike that was for sale, but when I asked a few concerned questions, the owners son started to yell at me and treated me like dirt, all because I noticed the mini bike was not his and in fact one of our club members motorized mini bike.
Even with had pictures to prove it was not his but my club members doodle bug mini bike.
When police were called by his mother because I refused to leave, the owners son ran off along with the mini bike and LAPD could not do anything without hard physical evidence
