'AH to go' (a mini version of the Albert Heijn supermarket) at Amsterdam Central Station is not only a very busy mini-supermarket, but also a very user-friendly one.

Here you can bring your bike without employees freaking out and you can also use the microwave self-service to heat up your ready-made AH food.

The label on the microwave reads: please pay before heating.

I am not sure the informal usage and ad-hoc setup is what the retail-designers had in mind, but it's nice to see people tweak things to fit their needs.
