I have no idea. If there are restrictions, it was not clearly specified on the menu...and it is the same menu for indoors and outdoors. I *think* they were trying to limit the menu for walk-up orders to quick turnaround items. Whatever the case, it was not clearly communicated.I don't know about your state, but Maryland has weird laws about serving food and running a microbrewery. They mostly do food trucks to get around the serving food limitations and then there are restrictions on where the beer can be consumed, etc. It makes no sense on the surface, but bigger crowds do not always equal more profit. More revenue? Almost certainly, but not necessarily more profit.
Like I said, we had a good rapport with the GM going into this. An idea we suggested: next time for our events, limit the patio sales to canned beer only. We could communicate that in advance and from the stage. Load up a big ice chest with a few of the best-sellers and set up a tap-to-pay POS. They could also do no food service outside unless people order online and pick up the order inside. Either that or offer a very limited menu. This would free up a lot of bandwidth for inexperienced staff who were working the whole patio trying to take orders, serve customers, clear tables, etc. The intent wasn't to change their entire business model, it was simply to streamline things for the once every six weeks they host a special, high-volume event.
