You might think, looking at this ad, that this gym had classes. Classes with teachers. (You might think those teachers could tell you about breast enhancement surgery, too, looking more closely at this ad.) Alas, if you went to this gym, you would find out that there are no classes, or teachers, only overly small rooms with screens and YouTube fitness channels. And four tread mills. 

Cheers to my friends who deftly handled my hysterical disappointment with coffees and speculoos cookies.
