I thought maybe Giordano's simply doesn't have the staff to deliver right now, not that it's unsafe to do so.
I live in FL (tourist area) and a lot of local spots have limited delivery options due to staff issues. Many are short-staffed due to Covid and have eliminated the option altogether or tightened up their delivery area. The restaurant industry has been hit really hard, even if FL was seen as "open" unfortunately.
Definitely agree there is little/no risk for food delivery in regards to Covid safety.
