I work for a luxury British brand, and we receive a very generous staff discount. When I first joined the company, I kept this discount between me, my mum, sisters, and sister-in-law. Unfortunately, my sister-in-law couldn't keep it quiet and told her sisters. Soon enough, I started receiving shopping lists from them (SILs sisters) with all the things they wanted to buy using my staff discount, this is ongoing and I still get requests from them every now and again - just to add instead of asking me directly, they go through my sister-in-law, which is frustrating and rude.
My mum nor my sisters have ever asked me to use my discount - probably because they know anything I gift them will be from work, haha!
With my sister-in-law's loose lips, she let it slip to my cousin one day who then asked to use it, so I agreed because it was a present for her daughter. Recently, this cousin and her sister who are travelling abroad soon, asked me separately to use my discount so they could buy gifts for their friends. This really irritates me.
I'm sick a tired of people wanting to use my discount and I'm angry at my SIL for telling everyone about the discount and I get nothing in return from anyone for it.
Am I being unreasonable?
