Come on Paul and WoodenHands....you guys are painting a grim picture of the Scottish hospitality.
I have been up to Scotland many many times, and always have found the Scots to be very friendly before the 10th pint (and subsequent chaser).
Thereafter they may as well be speaking another language, so I nod and hope to hell I am nodding for the right thing!
Oh....but if you are English, it probably would not pay to cheer to loudly for the English, a kiss (Glaswegian style) will be moments away.
