Question: On certain occasions, and to certain persons (ex.: like to room maids) is it more appreciated if you leave tips in Cuban money (ex.: 36 CUP, instead of 1.50 CUC)?
Answer: No doubt they would prefer the CUC since most of what they need to buy in the stores is sold in CUC. But they can purchase the CUCs at the CADECA change houses at 25 CUP for one CUC.
