People here (North Holland) are used to tourists and immigrants. A local could use “Hi”, “Hallo”, “Bonjour” or “Shalom” instead of Dutch-specific “Goeiemorgen”/other. If I say “Moin” or “Ciao” or “Hola”, people will understand and sometimes reply appropriately, but likely continue in English not Dutch. It’s something anyone would do for fun.
“hyvää huomenta” and “terve” on the other hand are not widely known to be a greeting. “tesekkuler” will not work as “merci”. I don’t do that.
