Counting the cost

Just catching up at home today after my travels. I worked out that the adventure cost me under £100.

Sheffield - Berwick - £0.00
Berwick - hotel - £10 taxi
Hotel, evening meal, a couple of drinks, £62.00
Hotel - Newcastle £0.00
Newcastle Bus Station- Train Station £7.00 taxi
Train ticket Newcastle - Sheffield £20.45

Enough left for a stick of rock for Mr PB.
