Many restaurants suggest tipping based on a pre-coupon / pre-discount total. The original bill would have been something like $40 with a 50% discount in a county with 9% sales tax on prepared foods. (sales tax is calculated with regard to the subtotal pre-coupon amount in the case of a percentage decrease and added after the discount took place). Tip is often calculated against the pre-coupon,post-tax amount.
40*1.09 – .5*40 = 23.60 (total as it appears on check)
40*1.09*0.15 = 6.54 (suggested tip amount for 15%)
40*1.09*0.17 = 7.84 (suggested tip amount for 18%)
40*1.09*0.20 = 8.72 (suggested tip amount for 20%)
So, my guess was off by a few pennies somewhere. Perhaps the sales tax in the area isn’t exactly 9%, or perhaps it was a $39.99 meal with a 50% off coupon, but you get the idea.

It’s easier than jihkro’s solution. They got $19.90 off, but calculated the tip based on the full amount. No VAT speculation needed.
