Places are starting to think minors are bad for business because they’re more likely to cause disturbances (and often hang around without spending money)
A lot of these businesses are creating curfews for unaccompanied teens after around 2/3pm on Fridays and weekends, banning them on Fridays/weekends altogether, and/or banning them in the afternoon every day of the week (although some of the bans, like at the boardwalk, are after around 8pm). Some are banning them outright.
