A funny story about this Supermarket Parking malarkey....
Many years ago when my local Sainsbury's Supermarket was built, they installed an automatic Car Park barrier, triggered by the car wheels contacting a patch in the road, which then raised the barrier...
This was all very well for 4-wheeled, wide-tracked vehicles, but no good for dear old Fozz with his trusty 2-wheeled Motor-Bike, which always failed to trigger the barrier!..

...!
As a regular, daily, shopper at the Supermarket (then and now) I quickly pointed out this problem to the the Big Chief at the Store who promptly got one of his minions to saw four feet (length) off the end of the barrier, just enough for me (and other 2 wheelers) to squeeze through the barrier, (which obviously remained firmly in the down position).
Wasn't that nice of them?...
Now you don't get that sort of personal service everywhere!...

...!
To thank them for their interest in my welfare, I now spend each day at the Store, carefully emptying the contents of my Purse, containing my weekly Pension, into Mr. Sainsbury's private Bank...
..and in return he supplies me with my daily Bread...(and Butter)..

...!
So we are both Happy Bunnies... [smiley=2vrolijk_08.gif]...!
Paul...Barriers never halt my progress... 8-)...!
P.S. Motor bikes normally don't normally have to pay parking charges for a number of reasons.... [smiley=thumbsup.gif]...!
