When you begin to think in terms of pesos, things become less confusing.
One of the most anxiety-provoking aspects of moving to Mexico and traveling as a single woman in my first months was handling money. I hadn't been to Mexico in over 30 years, the anxiety over the unfamiliar currency did not last long, a thirty-day phase perhaps, but the loss of equilibrium was astonishing.
It wasn't a matter of not knowing the exchange rate of the peso to the dollar. I didn't anticipate how the difference in the denominations and how the bills and coins look was going to throw me off so much.
If your Spanish is not good, a good argument could be made that purchasing things will cause you more stress than any other aspect of arriving here. You are often under pressure and don't want to look like an idiot. Every now and then, that will be used against you.
Cognitive dissonance of making transactions with bills and coins that look different from what you're used to can throw you in spite of knowing better. Inexpensive things cost hundreds or even thousands of pesos rather than tens of dollars.
Of course I anticipated the currency would look different, I just didn't realize how much my basic math skills had eroded.
Tips (propinas) are sometimes coins and I often felt I needed to give more, even when my math is good and I knew I tipped the right amount, leaving a coin didn't feel right.
Because it is still a mostly a cash country, grocery shopping feels like it must have felt in the Civil War South. You find yourself handing over a pile of bills with "big" numbers on them; 20’s, 50’s, 100’s, 500’s…..or $83.00, depending on how you look at it. Anyone would be well-served to study the money as well as the exchange rate when preparing for Mexico.
Only with experience will you know what 2,300 pesos really means in terms of value in Mexico, which is a little different from knowing that it's $139 dollars.
Simply knowing the exchange rate will not prevent some uncomfortable moments requiring that you take a deep breath, slow down and think calmly in front of sighing vendors, cashiers, and taxi-drivers.
At first, expect even your debit card to look unexpectedly foreign and ATM’s to take on an exotic air (avoid using other than bank A.T.M.s).
Your memory of common banking practices, pin numbers and login information can freeze up on you too. It is a phenomenon that a number of expats have confessed to me. Fortunately, it’s an alarming yet temporary condition.
In larger cities, banking is virtually the same as the U.S. If you have not traveled here in the last ten years, you may not be aware how convenient it has become. Thankfully in this regard, Mexico is no longer the Mexico of your college spring breaks. You can check your money online every day if you want.
A money belt was my best friend at first, not because I feared being robbed, but because I knew my house key and cab fare would always be there on my belly, regardless of how distracted I was by new sights and sounds.
Tipping, picking up an occasional tab or buying a round is routine here with my Mexican hosts and friends just like it is at home.
Tipping is 10-15% in Mexico and you learn to carry lots of five-peso pieces for grocery-baggers, parking space-savers and others who do small favors. A little haggling can be fun at a mercado, but don't get too carried away.
Don't be embarrassed if your math skills aren't what they used to be. Few people's are.
