I guess at the QR lounge in bkk it’s better to get new QR boarding pass inside the lounge to avoid hassles with the gate staff.
Seems like you overall enjoy QR so maybe it’s an issue of the specific rules. they can be hard to manage.
I’m surprised that Finnair was low on beer although perhaps it’s a DOH issue - we all know about Imbev / Budweiser and the beer issue during the fifa cup.
you could send a note to QR service about the rude gate staff at bkk and maybe get some points.
finally when denied Lounge access and seeking alcohol, sometimes the next best choice is to buy it retail and just pay the inflated costs :-)
