Awoman is sitting in her hotel room when there is a knock at the door. she opened the door to see a man whom she had never seen before. he said "oh i'm sorry, i have made a mistake, i thought this was my room." he then went down the corridor and in the elevator. the woman went back into her room and phoned security. what made the woman so suspicious of the man?

cookies! make chocolate chips, but with orange chocolate!

that is tough

explanation:

the answer is: give 30 chest compression

when we choke on foods, the pathway that we use to breath is blocked and prevented air from coming into our body. this could resulted in death within minutes after occurrence. because of this, after witnessing such choking accidents, we need to call 911 and immediately give the chest compression in order to open up a pathway for air to come in.
