you tip based on the pretax value of your entire meal. so, on top of $100 in this case

ahhhhh okay hahaha. mahalllll

your servers still need to get paid

hmm I would think its 50. not sure of its really abt pretax but 50 will also be ur pretax regardless, right?

you tip based on whatever your original bill comes up to

not sure how the coupon works. is it the kind of thing whetr they bill u 100 then u give them the coupon, or u tell them upfront abt the

coupon and they bill u 50?

say your bill comes up to $100, they still bill you that, but you don't need to top up more lor.
