Getting Overcharged In Shops Based On race or socio economic class

I don't know whether or not I should post a topic like this, but however I will. This has been boiling up inside me for quite a long time now.  Basically, I have had my hair braided a couple of times in the last few years I had it done for a reasonable price in Abuja. But, here in Ireland I am charged €100.00 and any other customer who is african or black is charged €40.00 I have had a relation of mine suss it all out for me.  Its understandable by all means that money has to be sent home to families in Nigeria etc. The issue here is not money (I am about to qualify as a laywer in May) the issue is, I feel as though I am being discriminated against and feel very disheartened as a result. It has also happened me in a number of food stores before and I kindly brought it to their attention and was issued with a receipt together with an apology. I was reluctant to report these incidents to the national consumer agency out of consideration for the ladies that owned the shop. Its like, if I ring up and ask for a quotation I get told the usual price and if you like, my sister in law phones about exactly the same matter and she gets a totally different price. Even if I ask for a price list its not possible for me to have that. I know it is indeed a matter for the national consumer agency, but from a personal point of view I think these ladies actually dislike me even though they are very friendly to my face obviously.  In the likes of Abuja, or anywhere else in Nigeria I have travelled to, its quite acceptable that I will be overcharged there as a tourist and in a developing country but to do it here in Dublin anyway,  what are your views on this?  many thanks.
