I tip anywhere from 15-20%. On business trip i can go up to 25% since it is paid by the company. However i dont go out much since the baby. If my food is shitty or i have to wait 15min after i asked for a check, you get 10%.
For chinese restaurant, it is typical not to expect good service unless you are chinese so dont be offended.
Obama will be slightly better choice even with his pro-gay swing. Rommey surely cant connect with the mass as he paid 15% bracket given his income is in the 7 digits. Shit, i make less than 6 digits and im in 25% bracket. Fuck me.
