I have lived in Glasgow for 5 years and I would say that route-wise First Glasgow gets me where I want to go.
The problems begin with the shelters - I agree with everyone else's opinions - they are usually non-existant or three-sided (why?) - considering Glasgow is the "rainy city" this is hardly wise. (But who are we to criticise the councils spending of our money?)

The second problem - and I cant shout this loud enough to newcomers THEY DO NOT GIVE CHANGE! I agree that they just have enough to do without sorted out change so I dont disagree with this policy - although if I could count the times I've had to put £1 in.......grumble grumble. But the worst is when someone gets on and starts arguing ceaselessly with the driver - when will First Glasgow listen - Advertise this fact much better than an inch high sticker on the front of the buses. Put it on the - rare these days - shelters.

A valuable piece of advice - after 4.30pm DO NOT go upstairs on a bus unless you absoultely have to - totally full of NEDS. (If you are not familiar with this term it means Glaswegian uneducated little thugs who think they are really hard but cant actually spell hard...)They have a habit of starting if they are in the mood - and believe me its the last place you want to be. Also upstairs will be full of smokers in the great unwritten rule that upstairs is smoking. NEVER tell a ned to put his/her/its fag out - they will maintain that they are not smoking! - with a fag in their hands!!!!!!!!???????? (Ned mentality!) and then start you.
But apart form all these gripes they do have good routes - but unfortunatley you have to know them, as there is no information at the bus stops and the drivers shout at you if you ask them questions. Ask someone at the stops as Glasgwegians are all friendly and will point you in the right direction.
Also - the prices of fares are inconsistent and depends on the bus drivers - you'll get shouted at by 1 f
or putting 70p in ("its 75!!!" they'll yell) and then the same route next day it 70p, then 80p and so on!
I still use them but i'd love to make Tony Blair take them to work everyday!!!!!!!!!!
