Now, about chips. You can double dip but you must turn the chip around so that the unbitten part goes in the dip. Two dips for potato chips and three dips for corn chips.
I have consulted my friend, and ~she~ feels this is still altogether too much chip handling in a communal dip situation. I disagree, but then, that is why we have this ongoing problem.
One solution to the three-dipping on tortilla chips (I'll give you two dips, but not three--that's almost spit-sharing time) is to buy the smaller round chips. That's a one dip chip for salsa or ccq. I will double dip potato chips if it's my own personal dip at home, but I do not want to risk the complete social humiliation of having someone publically announce that I have committed a social faux pas by double dipping at a gathering. The person who would be doing the announcement would be my #4 sister, the former cheerleader whose voice carries far and wide.
