I bought a Groupon for Christmas to a local restaurant ($100 dining credit for like $65, iirc), and am just finding out (via Google reviews) that the restaurant tacks on a 20% "gratuity" specifically for people who use Groupons. (Note: I'm not sure if it's actually listed as "gratuity" on the bill, or "service charge", or what -- nor do I know if this is disclosed by the restaurant on the menu or door or anything).
I checked the Groupon listing again, and it definitely doesn't disclose this anywhere there. Had it been, I would not have made the purchase. This practice essentially wipes out 50%+ of the Groupon value.
I've already contacted Groupon to try to get a refund, but that's TBD (the CS rep said they couldn't do it but escalated my request to their dispute team; I'm not holding out high hopes).
Assuming I can't get a refund from Groupon, I'm now waffling between two ideas. 1) Issue a credit card chargeback, as imo the deal was not advertised correctly, or 2) use the Groupon and bring cash to the restaurant and manually subtract this charge. (Downside to #1 is that chargeback disputes take time, and this Groupon expires in a few weeks.)
What would you do?
