Late bus

It was now already 2pm and we were keen to find the bus to the airport. I'd considered a taxi which was still an option but I wouldn't take one from the streets outside the station. We'd taken a bus here and just needed the same one back. We even had tickets. However, asking at various train ticket desks we got no help. Indeed we were told numerous times they don't sell bus tickets at the train station. But we were only asking for somewhere to buy bus tickets (actually I just wanted to check our tickets were valid). Eventually some elderly lady with an accounting book of some sorts open beside a bus stop points to round the corner where we go and recognise the same shape of booth where we bought tickets at the airport. We show our cards (a bit like paper Oyster cards) and they say they already have enough for the return journey. But they had only cost us about £1.50 for two! We make our way back to the bus top where we eventually work out we're in the right place after an elderly Spanish man is looking for the same bus and asks a local. But we must still wait half an hour with our bags on our back before it arrives.
