As a Canadian, I grew up getting used to throwing away money. Okay, not real money - pennies. In Canada GST is added to everything, so if a price tag says $2, the actual price will be like $2.28 (in Thailand, if the price tag says 143 baht, it's 143 baht). But the pennies that accumulate in the transaction were the bane of many Canadians' existence, piling up, filling pockets and jars, and generally being nearly useless (until they discontinued them in 2013). But that was nothing compared to the Thai equivalent - the dreaded satang coin.
