Disgusting and Disappointing bevaviour

Disgusting experience at the hospice shop in Scottburgh with my two kids. My kids, 4 and 6 years old donated about 30 teddy bears for the first time. It was a big thing for them to have sorted through their teddy bears and decide to donate them. We thought Hospice was a good choice, as we have always been donating old clothes and things to them. I took my kids to the hospice shop with all their teddies, and they were excited to finally donate them after all the motivation from their parents on how good an idea this is. We got to the hospice shop and the car guard helped us unload this mountain of teddies. She then led us into the shop and started taking the teddies to the back. I assume she know the staff and managers, coz they let her into the back without objection. Next thing I heard one staff member comment, "oh wow, my dog is going to love that big giraffe", referring to one of the teddies. My children stood there while the car guard kept returning to take more teddies out of their hands and disappearing to the back. I don't look for recognition or a pat on the back, but after making such a big decision, for them, not a single person thanked either one of my kids or even acknowledged them or the fact that they were there doing something "good". When the teddies were all taken to the back, we stood there and people, including staff looked at us as if we're standing in the way... so we started leaving. after we walked out, the guy behind the till suddenly shouted after me, as if in after thought, thank you for your donation. We were already out the shop and the kids out of earshot. Nobody even acknowledged these two kids after, for them, this big thing they just did. in retrospect, I deeply regret not turning around and taking everything back to take somewhere else. As we drove off, with every second that passed, I felt more and more sick to my stomach and disappointed with MYSELF for having taken my kids into such an ungrateful, disregarding, filthy-attitude place. My kids sat in silence, confused as to what it is they just did. You guys will never ever receive a single thing from my entire family ever again, and as far as I can help it, nor any other person I know.
