Stop in for a cup of coffee

I hated being at sea in the USN we were on a rotating 3 shift watch (1st shift) 00000-0400, (2nd ) 0400-0600, (3rd) 0600-0800, (1st) 0800-1200, (2nd) 1200-1600, (3rd) 1600-1800, (1st) 1800-2000, (2nd) 2000-2400. (3rd next day) 0000-0400 and so on 7 days a week and also then work your normal work times except on Sunday just watch. Do three months of that straight you are a zombie. Young mans game!
