Quo vadis?

Rather pathetically, it took me about 30 minutes to warm up, stop being paranoid and sketch a fellow customer in the Quo Vadis bakery cafe. The actually sketch only took 2 minutes. My poor general knowledge led me to check Wikipedia for the meaning of the phrase, Quo Vadis. It's biblical and I can't quite get the connection to baked goods...Maybe the point is "Where are you going? -Nowhere, at least not until I've had my coffee and buttered pretzel".
