It never ceases to amaze me just how many "shell-suited, chain-smoking, bling dripping travellers, and their under-age offspring, get tanked up in Glasgow airport and how often I hear last calls for them because they are "having a pint" and are going to damned well finish it before they condescend to board their flight.
Two points though, they are not all Glaswegians, but equally, I am sure that members throughout the country can give identical examples at their airport.
