When Angela Merkel was in Brisbane for G20 about two years ago, she famously went to a local bar for drinks. As in, wandered into a bar like a normal person and had a drink, like a normal person, with the other normal people one might find in Brisbane bar. Not as a publicity stunt or anything, but because she wanted to have a drink.
Obviously she had a minder or two discreetly with her, but the fundamental point was the chancellor of a major first world country could quite safely have a drink in a pub in another major first world country on a whim because she felt like it.
