That would be my suspicion; either food stalls, or, surprisingly, a stall selling meths, in very familiar-looking bottles (i.e. those just stolen from festival-goers). That or our CCE is simply a jobsworth tw*t, just like the jobsworths tw*ts at airport security who confiscate gas burners (e.g. Pocket Rockets) when there's no gas cylinder attached, and less residual gas in the thing than is produced by the tiniest fart.
A butane gas cylinder is a much better way of getting high. Or dead. Were they confiscating gas cylinders as well?
Definitely name and shame.
