How do you get to it from the pub though Yer?
There's a wall at that end of the bar afaicr.
The pub has two entrances on to the lane from memory. The fire (god forbid) won't block both entrances/exits before the alarm is raised. Once you're out onto the lane in good time it should be easy enough to avoid the flames.
I think a public venue with one single door would be very restricted in numbers it would be allowed accomodate, think the presence of stairs and overall area would be factors too. Similar sized venue with a door either end would have a much higher capacity passed by the Fire Brigade. There's a science to calculating the max number for given physical conditions afaik
