That's right! [...Oh, wait--] Did I not tell you about it before? My brothers and I have our own restaurant that we work at in the front of the building, and then the gym is located towards the back. As a result, we often get many customers that come for the food sticking around to watch any gym battles that occur that day.

[Hence the waiter outfits they were wearing in that memory. (Or even Cilan's own wardrobe of constantly wearing suits a lot even outside of the restaurant.)]
