Spiders Customer of the Day

So it's a normal working day and as per usual I'm dealing with various levels of stupidity, from people abandoning their 5 year old in the childrens book department while they go off to shop, to the lady who thinks I'm personally responsible for the fact that her carrier bag from another shop has broken and wants to know what I'm going to do about it (by the way sweet f!!k all is what I did about the latter), however neither of these receive my coveted prize.

Before I tell this tale however I would like to categoricly state that I do not discriminate against disabled people it was just for sheer arrogance and presumption this gets a mention.
Its about mid day and I've finally sat down to eat something (oh by the way as I've not previously mentioned this I'm the manager of this particular store and I seem to be one of those managers in the minority who slog their guts out with their staff, I dont do offices so I tend to eat on the move most days, to sit and eat is a great treat), when a member of staff, who is incidently a fantastic worker, comes up, apologises to me for disturbing me and explains the following problem.

A lady has approached her and told her she is completely blind, she has no guide dog, no white stick, and no helper, she has been given a pen as a gift but it is leaking, it is not a pen my company has ever sold. This lady is demanding a replacement refill and that my member of staff personally cleans this pen for her. At this point a few questions pop into my head
1. if she is blind how did she find my shop
2.if she is blind why does she need a pen
I deal with this nicely even though she is a rude witch who keeps bringing up her disability as a reason why she should be given everything for free (she can kiss my arse), we sell her a new refill and clean her pen as best we can with cloths and water as we dont offer a pen cleaning service we are not set up for it.
This is not good enough and we are mistreating her as she is partially sighted, (notice where she was once blind now she can see, a genuine f!!!ing miracle performed right in front of me). She is going to complain to my head office and report me to the relevent authorities (Im not worried however as there are witnesess to the fact that I delt with this lady with nothing but politeness and respect).
I mean if you bought some new clothes from one clothing retailer would you take them back to another saying these clothes are dirty and I'm disabled so you must wash them for me and if you don't I will complain- because essentially that's what happened to me and that is why this wins my customer of the day award
