waiting....with patient and patience

It takes a lot of patience in going to the doctor. First you have to cue to get your hospital number/record. You're late if you get there at 9.

The clerk calls the number in batch of tens

While waiting for your turn, you can seat if there is any vacant.

 And there is only one clerk attending to thousand.

Then he will give you another number, proceed inside the building for Surgery, Ortho, OB, Pedia, etc.

Same procedure as above.
