Adam,
 
Limestone is one of those stone that are very thirsty...especially after being suffocated under a topical for a while.  I have found that applying a couple of applications of sealer, let it sit, buff it, then apply another application a few days later sometimes helps.  He also MUST wait 72 hours before moping or allowing the surface to get wet in order for the sealer to fully penetrate.  (This is a disclosure on my contract.)
 
HOWEVER...It is very important to explain to your customer exactly what sealer is.  A sealer is not some bullet proof magical potion.  It is basically "Scotch-guard".  It buys you time to clean up a spill.  He might have the wrong idea of what the sealer is meant to do and he also needs to know which spills and cleaners will weaken the sealer.
Just my pennies worth.

Adam,

Besides being your company policy I don’t think there is any legal reason for you to return any money to your client. He hired you and payed you for the services that you performed improving his property.
His issue now is that the floor is still absorbing liquids after 2 coats of sealer was applied.
At this point  your process doesn’t matter but I would tell the customer that you felt you had applied a sufficient amount of sealer evidenced by your final testing . However once the product  cured and the solvent evaporated the limestone is so porous that it simply needs additional sealer. I would put in writing all the facts including that you are more than willing to apply additional sealer at your expense and time to correct the issue if possible . Include in a clause stating the stone may be technically impossible to seal(see what Fred says). Show the letter to your lawyer before sending. 
 Consider finding a sealer formulated for very porous applications. Maybe even one with a warranty if its possible.

Do an area for your customer, let the product cure and check the results.

You will have needed more coats w a solvent sealer. Keep coating til stone doesnt absorb. Should use a thicker sealer though.  Solvent is for less porous stones.
Bottom-line - bad stone choice for kitchen and wet/product-prone area. Stone will always etch with alcohol and acid. If not sealed thoroughly/appropriately you will have these issues.
I would attempt to poultice his stains and then seal with a porous stone sealer (511 porous plus - for example).  Sealer needs to dwell for atleast 15-20 mins before next coat. Keep applying till no more bubbles. Buff last coat to remove tackiness.
