The St Lucian culture follows England, with a 10% service charge added to many bills. So tips are not nearly as expected as they are in the United States. We frequently add a bit, especially if they were extra-pleasant or did something extra for us. If our bill doesn’t show a service charge, or we aren’t sure, we still tip, but usually 5-10%. The average hourly wage in St Lucia for those in the tourism industry is about the same as a Starbuck’s grande latte, so we know a little extra is appreciated.
