What i struggle to understand is why a global pandemic changes people to make toileting, rubbish leaving, hostility to police, ambulance crew, litter pickers etc acceptable. I don’t recall all this being an issue on hot sunny days before the virus
In hot sunny days before the virus all of the shops were open, pubs were open, there were museums, aquariums, softplays, attractions, hotels/B&Bs/holiday parks, cafes, restaurants, etc. So all the mass groups of people were more spread out, there were extra toilets available in cafes/pubs, venues had extra staff taken on to cover the additional work during the peak season and the peak would ebb and flow based on weekends, bank holidays, school holidays.
Yesterday (and throughout lockdown) there was a mass of people concentrated into one specific area - the beach - as there were no pubs, cafes, other attractions, etc to siphon any of them off elsewhere and spread out the concentration of visitors. No extra toilets as no venues open so only the public toilets available which are enough on their own to cope with that amount of people. Add in alcohol, heat, the emotional and mental fall out of lockdown, and you have a lot of hot, frustrated, bored people. Some of them will be nice people who wouldn't dream of shitting in a garden but unfortunately some of them aren't and when the usual amenities aren't available those people develop a "fuck it" mentality quickly followed by those who think "well if everyone else is doing it...".
It's not that tourist areas don't want people back, despite the negatives of extra waste and antisocial behaviour, it's that they don't want them back until the fscilties and infrastructure are in place to cope with them which wont be until 4th July at the earliest.
