Aaahh, the old memories. I was a postal clerk in Dallas for 5 years and was working a window selling stamps and such when the price of first class stamps went from 4 cents to 5 cents.
Trains, busses, and trucks hauled that mail; airmail stamps cost way too much at 7 cents, and if you had something that was really urgent, Special Delivery was 30 cents. And of course, the Post Office handled all the parcels, too, since UPS, FedEx, and DHL didn't exist. And yep, people complained about the high price of stamps back then, too. Of course, with no Internet, more people wrote letters and sent postcards; yep, lots of folks complained about having to pay 2 cents for a "penny postcard". And my starting salary as a parttime letter carrier was $1.84 an hour. But by the time I started full time as a clerk, it was up to $2.00 an hour.
But as many others do now, nearly all my business is conducted via the Internet. I've written one check so far this year (to buy a car) and 2 checks last year, but none of them were mailed. Stamps are only for my wife to send greeting cards; i.e., Christmas, birthdays, anniversaries, Valentines, etc.
