Nice visual esp while I am eating!!! ha haWe don't have In-N-Out here...I was on a business trip to Vegas and my boss (dufus) went there and got burgers for us all (big spender).
Lets just say that in-n-out is well named...it went in and about 30 min later it came back out. yuck. Nothing is grosser than re-tasting a in-n-out burger....nasty...shudder...
Must have been the location you visited. NEVER in my 37yrs had that experience and I've been eating em all my life
