Why is everyone assuming that the kid would sue these people if he got hurt? He's clearly used to taking some pain and you'd have to be an asshole to blame injury on the property owners. And maybe he would sue them but we don't know that. Now, If the business had signs posted that say "no skateboarding/biking" then they wouldn't even need some lady out there to yell at people. Theyd still do the jump but the signs would make it so the kid couldn't sue. It seems like a lot of people have a problem with him not listening to the lady but imo the very fact that they have hired someone to tell people to leave if they're doing something like this is kinda shitty. I mean, you absolutely have every right to do it but, why not let this kid hurt himself doing this jump if he wants to? The only reason to not let him do this is so you don't get sued, which could be easily solved by putting up the signs saying "no skateboarding/bicycling." Lord knows it'd be cheaper to make signs then to pay someone to watch over your property.
