Our son was unlucky that the chain of his bike was coming off. We stopped by Fiets Centraal and thought we would put the chain on it. To dismantle the chain guard, tools were needed and he obviously didn't have that with him. When asked if they could help him, the answer was clearly NO, we are too busy. Borrowing tools was still allowed. Unfortunately he could not manage to dismantle the chain guard. However, as said, help was not possible. But yes, he had to go home, the lesson car would drive ahead and missing a lesson is also a costly affair. After a phone call from Pa, some help was still possible. The chain guard was dismantled by loosening 1 screw on the chain and paying for it, 5 euros for the effort. Fortunately, he was able to cycle home and the driving lessons were not missed. It is quite understandable that larger repairs cannot be carried out in a minute. Offering a loan bike and carrying out the repair later is fine. Allow a customer to stand and walk for miles? No, you really miss the mark.
