It is somewhat ineffecient spacewise. But my area tends to have fruit fly problems during the summer, so we use the smaller plastic bags to more tightly seal food waste to keep fruit flies from getting to it. Also reduces odors from the trash

Same here. I started doing it as a silly thing to tease/bug my girlfriend but now it’s become a permanent part of my personality. I will now only say “jadies and lentlemen”, and I did it so frequently that she says it too.

For me, the biggest factor is the quality of the coffee. If it’s too good (in taste) then there are more oils which break the foam. But if it’s too bad it will have barely any taste. Awhile back I found a really good instant dark roast that had good foam and good taste but it’s gone now. The coffee I currently use is fairly good though. This is how much foam I get from it, with one spoonfull of coffee:

Love the Greek Frappè! I prefer using a milk frother rather than shaking to make the foam; I always get thicker foam that way. If you do shake it, you should add the ice beforehand. Even better, cut out the ice and add vanilla ice cream instead and it becomes a great dessert!
