Peers had a habit of calling me for non-critical, non-production problems. The worst was Mardi Gras, where I'm on Bourbon Street for Fat Tuesday, and my operations head calls me with an analyst on the line and burns fifteen minutes with a problem that turned out to be development coding.
My phone did occasionally explode with voicemails and texts when I got back to port.
Some of my peers have been forced to take a corporate credit card to pay for internet access on their ship.
