What I find odd is that he signal at the bus station is worse than it is at home - and the bus station is LOS to the tower and not far away.
Masts that give maximum range don't really work like that. The signal is likely to be stronger a little further from the mast than right next to it or directly below. That's just down to the radius of the transmission. So in the pub, assuming it's straight below, that might be worse than say 50m down the road for example.
The higher a mast, the more this occurs. So these LTE masts will definitely experience this phenomena. I live 70- 100m from a mast and standing next to it I get -70 on my iPhone, whereas in my house upstairs I get -60 (so a stronger signal, yet further away, a couple of streets away actually).
Also bus stations will contain two materials 1) Metal and 2) Concrete
Both of which are basically the death of wireless and will severely severely hinder the signals.
Then there's 3 transmitters, so in some areas you're not going to have a directly straight line signal to the transmitter which can severely reduce performance.
It's difficult to know where the optimal point is however a good way to check is to go onto your iPhone, go to make a call and enter *3001#12345#* press call.
Your signal changes to a number. -55 to -60 is around maximum signal and -120 is very bad. It will often hold onto -130 but below -120 data is unlikely to work well (if at all) and calls will be all over the place.
