#93: Most American Spanish-speakers don't care about the flag of Spain
If you have third-party services (a self-check machine, a computer reservation system, etc.) that offer languages other than English, check and see if there’s an icon representing each language option. If there is, and there’s one for Spanish, check with the vendor to see if you have the option to customize what the icon looks like. It’s very common for vendors to use the flag of Spain for Spanish, which isn’t intuitive for most American Spanish-speakers (imagine having to select a picture of the flag of Great Britain to get an English option). If possible, find out where the plurality of Spanish-speakers in your area have roots, and swap the Spanish flag out for Mexico, Puerto Rico, or whatever is most likely to suggest ‘that’s intended for me’ to more of your particular patrons.
