I watched an episode of Time Team recently, which involved searching for further parts of the best-preserved Roman town in Britain (I can't recall the name of the town, but it's in Wales).
The team found further shops, including what was probably a butcher's shop, and the comment was made that many Romans in Britain were complaining at the time about cheating meat-sellers who tried to pass off old mutton as young tender lamb. It was rather funny when old sheep bones were lifted from the dirt in the Roman layer of that shop...
