We have heard many arguments against the new multi-space parking meters, and indeed the campaign appears to have been successful with the reinstallation of single units taking place this very morning in Coolidge Corner. I never saw my own beefs against the multi-space meters aired, but they are no less important in my view.

We have heard many arguments against the new multi-space parking meters, and indeed the campaign appears to have been successful with the reinstallation of single units taking place this very morning in Coolidge Corner.

I never saw my own beefs against the multi-space meters aired, but they are no less important in my view.

First of all, I had to touch the touch screen, and then raise the flap to get my receipt, after untold other people touched them as well. Call me over-obsessive, but until public hygiene is pristine, with adults and kids washing their hands regularly (just do a quick check next time you are in a public bathroom, and also observe how many people touch door handles), I shy away from public touchspots, or use a napkin — which you can't do on touch screens.

Second, many people may be unaware that receipts contain BPA. I know this from my work in environmental and public health groups, but this fact was also mentioned last week in an ABC-TV feature segment on the toxic chemical. (Soon, smartphones will receive emailed copies of receipts from many stores that are trying to do away with receipts — but until then, wear a latex glove, or stuff your receipts into a napkin. Try not to touch them, and if you do, wash your hands afterwards).

Of course, coins are none too sanitary either, but at least they are my coins. And the new single meters will also take my own credit cards.

So here's to better public satisfaction, with a dividend of better public health, as well. — Susie Davidson, Winchester Street
