On Thursday I drew out 300e from a Cam bank machine, it wasn't Servired but did show the Visa sign. The machine showed a Euros to £ rate of £247.48. The next day I drew another 300 at a Serivred machine and the rate was 245.51,
Both items came through to account today and I paid the same for each £240.95.
Not sure if the rate dipped yesterday, if this happens on all Visa machines or just Cam Bank trying to gain extra money....lol
It's a good example of why you must get an atm card which is free to use abroad and answer the question correctly if prompted to do so. The first withdrawal I made was from a CatalunyaCaixa Servired machine and that one didn't ask - very speedy transaction.
