I have a family member whose celebrity probably peaked at mid-B-list in the 1970s or 80s. One time in the 90s we went to a restaurant in NYC that wasn’t fancy, but was new and pretty popular. They didn’t take reservations. When we arrived nobody recognized her and they told us the wait would be an hour for a table.
She grabbed a matchbook with their phone number on it and we walked around the corner to a payphone. She dialed and in a heavy New Yawk accent said: “This is Georgette from [her name]'s office. She’s on her way to your restaurant for dinner and I TOTALLY forgot to call ahead to make a reservation. Can you still squeeze her in when she arrives?” We walked back around the corner and were promptly seated.
