With all due respect to my fellow physician - In the course of my own investigations, I have formulated the hypothesis that “plastic finger syndrome†is merely a secondary symptom of the much more fundamentally dangerous "credit card prolapse". Which, I now firmly believe, is one of the few shopping related disorders to be *made worse* by the consumption of alchohol!
I have, however, seen many cases where the symptoms of "1st Shop Disorder" are clearly displayed (the throbbing vein, the fixed smile, the tightly clenched jaw and compulsive watch gazing).. to these patients I have recommended my own particular brew (2 parts vodka, 1 part Kahoola and a dash of milk over ice - to be taken approximately once per hour, until unconcious), by means of treatment.
