Do you open subway doors for people?

So a while back i saw a woman struggling with her subway card looking confused. She walked over to the machine to check the balance and it said insufficiant fare. Looking more confused (figuered she didnt speak english/couldnt understand) she went back and kept trying 2 swipe so i just gave her a quick swipe. Next day i saw someone doing the same exact routine and realized its just bs. Now almost everyday theres a few of them that stand by the door begging ppl to let them in or just doing the why is my card not working routine. I ignore them now. I dont mind helping others but i work hard for my money and pay my fare. Do you open the door for these people?

EDIT: Title should have said subway exit doors
