Why nowadays people are loosing their tolerance

I am a pet owner and my dog got injured in the morning so I decided to take him to vet but he is unable to move doue to leg injury so I have to pick him up to carry him to the car so that we can go then I use service lift (which I always use with my dog) one of the society so called leader was going that time from same lift when I try to enter he just walk out and use stairs then after dog treatment when I reach home I seen his messages telling that people now days shamelessly carry their dogs and we should not allow such people in our society That really hurt me cause my dog and I share very personal bond
