Fenway Park concession workers are looking to strike out grab-and-go beer coolers and self-checkout kiosks due to rowdy fan behavior, but the Red Sox say they haven’t received any violation notices. Members of UNITE HERE Local 26 are making their plea to state lawmakers that alcoholic beverages should only be sold under the direct supervision of ballpark employees, eliminating self-serve stations. “So, why are they permitted at large venues?”Aramayo and concession workers made their pitch to the Joint Committee on Consumer Protection & Professional Licensure. David Friedman, executive vice president of legal governmental affairs and chief compliance officer for the Red Sox, pointed out how workers supervise the self-checkout stands. He added that there are just six such stands inside Fenway, with Aramark concession workers processing transactions at the others.
