Someone who can wait forever and not yell about it. They’re the kind of person who can sit through a 3-hour movie without complaining.

'He's a patient, and he can wait for hours without even blinking.'

'She's a patient, and she let the doctor wait for her for 20 minutes.'

'That patient didn’t even yell when the doctor made him wait for an hour.'
