The M&S food store in Guiseley doesn't have cycle stands. It does though have a massive car park. You could try chaining your bike to the trolley racks but this would get in the way.
M&S advertises its environmental and ethical morality. Food is sourced sustainably, their lorries are nciely rounded to reduce fuel consumption etc, but should you actually want to spurn that most environmentally disasterous choice of the motor car, in Guiseley at least, you are out of luck.
