This is 3-4 times more than the locals would ever pay.
My Laundry Cost More Than Guatemala Workers Make in Day
You have to watch out for the gringos and English speaking people MORE than the Guatemalans when it comes to rip-offs! "Everyone" is so eager to "be your friend" when you first get there, as they are laughing all the way to the bank. Good points about "try to do the math!"
"Muy Caro!" or "Carisimo" = VERY EXPENSIVE! Say it one time and the price will automatically come down. Say it two or three times and offer 1/4 of what they are asking. Then you will pay the right price.
Thanks Catherine, always nice when a long-term visitor to Lake Atitlan helps collaborate. In the end "try to do the math." Knowing most countries the people earn 7-15 dollars PER DAY.
