Former CPA firm I worked for was nothing but death fats except me and the secretary (that eventually became my wife).  When I had to go out in to the field with the others for audits, it was disgraceful and embarrassing to dine with them.  They'd rack up $60 easily apiece and only tip the watier/waitress a $1.00.  This happened no matter where we went.  I always felt guilty and would tip more.  Meals weren't a reimbursable expense for us in the field as "everyone has to eat" according my ex-employers.
