How can I change my 2000 baht in small coins before leaving Thailand?

If you have around 2000 baht in small coins (1 and 2 baht) before leaving Thailand, there are several options for changing them into bills. You can bag the coins in 100 baht plastic bags and take them to a 7-Eleven or a Family Mart, as they often exchange coins for notes. Alternatively, you can exchange them at banks, but make sure to bag them up first. If you prefer not to deal with the hassle of exchanging, you might consider donating them to a local charity, giving them to street people in need, or even using them to buy snacks and souvenirs. Many commenters suggest that giving the money away is a good deed, as it may benefit those who need it more than you do.
