Gesture & etiquette
Point subtly to the tattoo area if it helps convey the size/location, or just look sincere and respectful.
Always ask, rules vary between establishments. Be prepared for refusal or the requirement to cover it up (e.g., with a cover sticker). Do not enter without asking if you have a visible tattoo.
