Glasgow memoirs : First bus ride

Oh yes, there were couple of more interesting things today - like the visit to kelvingrove park (we couldn't enjoy much since we were totally worn out after the 9 mile walk and hungry as hell)  and sighting a hindu temple (they offer free vegetarian food! But it was 4 hrs away..  Thanks for the offer God, but may be next time)...
So after bugging a very sweet and polite lady at the bus stop (God bless her), we got to know the nitty gritties of the bus system.. that we need exact change when we board to get the tickets. She speculated hard and calculated that we would need £3.90.. We fumble through our pockets and somehow manage to add up the exact change...  And then God decides to play some really funny games with our already hungry and tired souls..
So when we board the bus, the driver asks us to pay £2.40.. With a really sweet and sympathetic smile..  I just looked at all the tinkering pieces of metal in my hand with pics of the Queen in varied sizes.. And looked at the driver helplessly.. I mean.. Someone must be in a jolly good mood to design a miniscule coin for a pound and a very big, valuable looking coin which is a peace.. To make it worse, an even bigger coin is 20 pence... And all the denominations are in words, not numbers!
Anyway, wet somehow managed to pay the.. Yes.. EXACT change..  To a huge relief of the rest of the crowd in the bus...
So tonight, we have cancelled our dinner date and instead will study 2 things - 1. bus timetables and 2. How to identify a coins denomination by just looking at it...
