The passenger was in extreme pain and had a legitimate need to exit the plane quickly to secure a wheelchair. The other passenger's luggage being further back in the plane is not the disabled passenger's fault. While some inconvenience may have occurred, the disabled passenger's health needs should take priority, and the reaction from the other passengers was disproportionately rude.
The passenger, despite their disability, still inconvenienced other passengers. Claiming a wheelchair doesn't give them the right to cut in front of others or disregard common courtesy. The fact that the other passenger's luggage was further back is irrelevant; the disabled passenger still created a disturbance and should have waited their turn or asked for assistance more politely instead of rushing off the plane and causing further issues.
While the disabled passenger had a valid reason for wanting to deplane quickly, their actions did cause inconvenience to another passenger. The other passengers' reaction was also inappropriate, resorting to passive-aggressive behavior instead of addressing the issue directly. Both parties could have handled the situation with more understanding and respect.
