To anyone coming out to Greece in the near future: might be an idea to bring euros. Due to the banks being closed, head office can't, it seems, get access to money to fulfil the exchange needs, hence we're limiting exchange to £60 maximum. In Skala office we're interpreting this as per person so a couple wanting to exchange £100 simply do £50 per person. No idea what other companies are doing but some could, *possibly*, run out of euros to exchange.
Other than that, everything seems to be functioning as normal, no queues at the ATM opposite, which seems to be working OK, and electronic transactions OK.
