Office hour

I have to have at least one office hour per week for the class I am teaching. Not having an actual office, for the office hour I sit at the local coffee/pastry shop. After announcing like 20 times to my class that my "office hour" will be at the coffee shop, I realized that I was implying that the coffee shop was in fact my office. The next time I announced it, I muttered that my office hour will be at the coffee shop, "where I also sell delicious pastries." They thought that was funny. So now, whenever I announce the hour, I talk up the "delicious pastries" and "refreshing beverages" that "I also sell" at the coffee shop. But they don't laugh anymore. Weird, huh? 'Cause now I am getting really into this whole owning the coffee shop scam. I might start using "my" coffee shop as an example of things in European history, like how the Bolsheviks initially let the peasants own their own farms, just like I own "my" coffee shop. Though that doesn't make complete sense, because "my" coffee shop is a national chain.
