Excellent cartoon. A simple observation regarding currency exchange on most recent trip to Thailand and Hong Kong.
Exchange rate in all exchange booths in BKK Airport was ~2.05 baht less than mid market rate (~7.7% commission) which is ~1.8 baht less what is on offer in Pattaya and some Bangkok exchanges which offer ~0.25 baht less than mid market rate. CNX airport was ~0.8 baht better than BKK airport and there is at least one exchange in Chiang Mai that offers close to the best Pattaya exchanges. I learnt a long time ago to bring back enough Thai baht with me to last me for 2-3 days on next trip without needing exchange.
Travelex is the only exchange in HKG and was offering ~0.6HKD less than mid market rate at ~1AUD=5.09HKD (~10.5% commission). The interesting part was using the ATM machine I was offered ~5.50HKD but musn't have had any money I could use for cash advance on the 28 Degrees card.
And I will never understand the greed behind not allowing free pick-up or making it extremely difficult for free pick-up. SYD airport is one classic example of that greed.
