3 local pubs got fed up with a trendy bar getting planning permission to have their curtilage parking converted to a large outdoor seating area so that they no longer had any on-site private parking. The trendy-set loved the new terraced lounge area so much they bar flocked to it at weekends and evenings. So much so that the other pubs, a restaurant, the supermarket, an apartment block, a hairdresser, the Methodist church, a solicitor, a B+B, and a cyclists' cafe all reported that the trendies were leaving their cars in their car parks to spend the evening in the trendy bar.
Result? Signs were put up warning people that they would get clamped if they weren't visiting the shops/ pubs of the car parks they were parking in. The rival bar patrons continued to trespass on the available parking.... so the other shops and pubs pooled together and hired security to monitor and charge people . The trendies then complained to the Council that they had nowhere to park and started campaigns on social media to humiliate the rival pubs- one went bust as a direct result of all the abuse they received.
Please respect shops and pubs' privater curtilage parking - they pay rates and maintenance and provide parking as a service. If you abuse it they will; bring in enforcement which only causes stress and aggravation.
Let us know how that goes as I've never tried it.
