I recently met a friend at Edinburgh airport
we both arrived much earlier than we needed to so that we could have a catch up

she does not have BA status (rarely flies BA ) but she has a priority pass issued by her bank (cardholder + 1 guest ) so courtesy of that we spent some time in the servisair lounge ( and hey I got a stamp on my card thingy )
we then headed to the BA lounge were I guested her in

did we break any rules ? no we did not

did we break the rules of the morality police ? yes we probably did

do I care ? not at all
