You know when you purchase coffee at coffee joints like TCBTL
and Starbucks, the service crew will ask you for your name or an
initial?
What do you usually tell them?
Do you really tell them your name e.g. "Bee Hoon" or do you give
a pseudo name?
Usually I just tell them to put a "Z" on my cup, but I'm always
so tempted to tell them bizarre like "My name is Potato." 
i just tell them "rachel" easy wat
