People drink all the time. It’s the person who is responsible for their actions. Blaming a concert is like blaming an adult who play a video game to act out. They are adults and have done this 3 times now at different concerts.
Official statement from PNC Music Pavilion:
“We were saddened by the regrettable events that took place on Friday, June 17. Upon learning that the offensive actions were taken by patrons who also happened to be employed by Lucas Landscaping, one of our service providers, we took swift and immediate action to terminate services provided by Lucas Landscaping at PNC Music Pavilion.”
