You get the likes of Central Taxis who's whole bus operation is based on contracts from both Nexus and Tesco. Each time they gain a range of contracts, the investment goes in for brand new buses. Maybe they don't have all the nice tech the big three have on their buses, but they offer a service that gets people to their destination.

Sometime later down the line if budgets are squeezed any further, I wonder if the big three operators will put their heads together and think adding the likes of Tables and nice seats isn't really worth the hassle when most passengers will still travel with them regardless. I agree Wi-Fi and USB Charging Points are essential for the majority of passengers, however I think most people will more than happily go without if it means they can have a bus service still running...
