I am in the category as described and have had no problem,so far, with EZY or indeed other carriers. I think its someone on the ground staff either being pedantic, a lot of them are, or just simply didnt know what the carriers rules were, more likely.
The be honest, the staff of any carrier, do not look inside clothing or cabin baggage, thats the role of the security checkers who operate to Government (ok occasionally their own as well) rules and have no idea at a busy airport which carrier you are travelling with.
All carriers have these regs in case something crops up and they have to give definitive answers. Its called belt and braces approach but for the most part if the traveller is discreet,so are they...They dont want to bite the hand that feeds them
Happy flying
