Budapest market

Final day of holiday. Free time to wander around the city and discover how people today live their lives not like the sanitised history we are given on our daily tours.
Am worried by all the coughing and spluttering around on the boat.
At no point in this tour have we been asked to show vaccination certificates or asked to take a Covid test.
I suspect if they did and people tested positive on board it would cause panic. Instead they are letting it rip.
