We had a few groups in Melbourne (Aus) do "flash protests" in certain stores late last year.

(Mandates had been applied, so that people could not work unless they were jabbed to date, and all the stupid checkin masking stuff remains...)

They would all barge into a K-Mart, maskless, get trollies, fill them up, chant and shout freedom slogans, go around the store before staff could respond, then exit leaving the trollies with merchandise in it.

(This works here, because in-store crime is low, and virtually no stores have armed security or anything like that on hand.)
