Market in Teguise. How much? – I asked pointing at a big mask. Where you from? – the African seller replied. Is the price based on nationality? – I thought. Poland – my partner replied. These cheap ones for 40 euros – he pointed at small masks. What about the big one? – I referred to my original choice. These are expensive! 120 euros! These must be just for Brits or Germans – I had another thought. How much do you give, my friend? – He clearly read my mind. 20 – I replied. My last price 40, my friend. Polish price. 120 for Brits and Germans – he added.
