id say good riddance. someone that quits right in the middle of a job? that's no good. if he was one of my guys, hed receive no pay for that day, and no good recommendation if a future employer calls. find you some real help, that's about as sorry as you can get. he could have at least finished the job.
My set up:
-2007 Chevy 2500hd 8.1l 4x4
-7x18 enclosed trailer
-Grasshopper front mount 61", gravely 52"
-36" Gravely Walkbehind, 21" exmark push mower
