At least half a dozen times in the past three days I’ve been so annoyed by the payment process for various goods and/or services that I either didn’t purchase the thing, or had a minor meltdown after the whole ordeal was over. Why do merchants insist on making it so damned difficult for their customers to get the goods? A few frustrating examples Ever been to a sporting event where the beer vendor only accept cash, has no cash-register, and yet insists on charging a partial dollar amount per unit of booze? $6.65 for a beer… really?...
