hiya , im wondering about this a lot, the best gift ive given was a "traffic warden voodoo doll" was about £4 and a birthday presant to my best freind who has terrible time with the tws.shes got a blue badge and was given a ticket for paking in a disabled bay, took weeks to sort out.so has a mini hatred for all traffic wardens.she still hits hysterical laughter everytime she sees a tw, months later.(sorry to all tws out there, im sure you are lovely people,and you are just doing your job)
