How easy is our job !

I have been to a railway reservation counter recently and while standing in the 'Q', i was wondering the amount of patience the executives there should be having. They need to interact with sooo many customers, with sooo many queries.. each having their own requirement. On an average, the executive must be handling at least 10 people in an hour and just hats off to those people. Same is the case with all those people who interact with the customer for soo long, like doctors, sales executives, etc., They may love their job but still...
In comparison with the software industry where the client interaction will be every now and then or at the most once per day and for that only we may get frustrated at times... we will be nowhere to these people.
