I can speak enough Greek to be understood in a bike shop. What follows is a transcript of our Greek conversation.
ME: Do you have "patch kit"?*
CLERK: [Greek I don't understand, but she doesn't understand "patch kit."]
ME: I look. [Literally, βλέπο ("vlepo") which is the verb form "I look", but which I hope implies "I am looking", as it does in the phrase "μόνο βλέπο" ("mono vlepo"), which is "I am just looking," a phrase you can use to drive Greek shopkeepers crazy, since they mainly hear it from English tourists. Greek scholars, probably including my lovely bride, may now giggle.]
[looks around, finds a patch kit]
ME: How much is this?
Me: OK! [pays]
SECOND CLERK: [question I don't really understand, but is probably "do you want a bag?"]
Me: No. It is ok. [puts kit in jersey pocket to demonstrate that yes, it's ok]
Me: Thanks, good day!
As you can see, my Greek is amazing, running to a vocabulary of at least two dozen words.
