Maybe it's bimbo of me that I found it VERY VERY hilarious that my brother suggested that I use the name FiFi for my drink.
When I heard the barista call out, "One Toffe Nut Latte Venti for FiFi!!!" I can't help laughing and dropped my receipt. I must have looked really really stupid.
Apparently, that's the name he suggests to use when others ask him. (And I know the previous sentence is grammatically vague)
