I will never give blood again!!!

I have been giving blood for the past couple of years ... today, I went to donate blood and because I had gone to Thailand in April this year, the lady that I was unable to donate blood for the next 3 years as it was in a malaria area. Upon my return from Thailand, however, I went for a malaria test as I wasn't feeling well. Turns out I had contracted COVID upon my return. My malaria test that was done came back negative. The worst is I gave blood 3 months ago!! I then went to speak to the lady at the front and must say that I was not impressed at all with her atttitude ... what you need to remember, lady, is that without us, you wouldn't have a job ... stop thinking that you are so high and mighty. I have now made a promise to myself that I will NEVER EVER AGAIN donate blood.
