1. How would she know what amount to have on hand to give someone change?
2. There is a safety factor here and I couldn't pretend to have enough knowledge and expertise to lecture others.
 The bottom line I've learned so far is, there are people who will take your wallet containing the adorable family pics you treasure, every dollar, credit card, health ins. card, Triple AAA card, identification, cell phone, laptop, luggage, clothing, Ipod you created a cute lil playlist on to enhance your guest's visit, auto/house/whatever keys, hotel room towels, GD Liliputian-sized hotel toiletries, four-star linens, pillows, radio, flat-screen tv, glasses, mugs, coffee-maker, ice-bucket, hair-dryer, bathrobes, closet hangers, shower curtain, lamps, art, side tables, balcony furniture, toilet paper, and anything else that isn't bolted down, at knife/gun point. And yes, even the Gideon's free gift in the top drawer.
  Whatcha gonna do? Call hotel security? The authorities? Your mom and pop?
 Might have to reimburse the hotel for their property loss. Why not protect yourself from Identity theft, the hassle of canceling EVERYTHING, your personal info and client info. from falling into the wrong hands and whatever cash you might have on you, that could at least pay for a box of tissues to cry into and a cab ride home?
  I never want more than 8.00 bucks on me and that is almost always in quarters. Gotta have "change" for the beverage machine when I need a lil Diet Coke/caffeine pick-me-up.  
  So, if anyone wants "change" for the laundromat, I'm your dreamgirl!  
She did her part. You know the amount before you arrive.
                                                                  Peace.
