I hate waiting in long lines to resolve a problem. I always consider reasonable alternate strategies, such as calling an agent on the phone. For example, when my arriving flight was sitting on the tarmac at ORD on a night with bad weather, waiting for a gate to become available, I started working the system from my mobile phone:

• I called the airline and learned that my connecting flight had already left.
• I asked if they could endorse me to another carrier leaving later that night. They said nothing available.
• I confirmed a seat on a flight the next morning. I switched to a 10-ish departure for convenience instead of the 0630 flight they initially offered.
• I inquired about hotel allowance and learned that there would be none because weather was the culprit.
• Next, I called a popular hotel chain and booked a room at the nearest hotel with availability.
• Finally, I called the specific hotel and asked about their airport shuttle. I learned that it would stop running by the time I arrived in the terminal.

As a result of this planning, I passed through the airport pretty quickly once the flight deboarded. I noticed the huge line of people at the airline service desk. It was easily 200 people long. I saw frazzled faces and heard raised voices. I walked straight past it. I also walked straight past the hotel shuttle area and went directly to the taxi stand. 40 minutes after the aircraft cabin door opened, I opened the door to my hotel room and began winding down for the night. My fellow passengers who joined that customer service line were probably still waiting for help.

That depends on the nature of the advice and the credibility of the person offering it. What are you getting at?
