This is the WORST USPS I've ever experienced. The Hispanic (Mexican) supervisor "mistakenly" entered all of my information for an international package, BEFORE he "discovered that some items I was shipping were restricted by that country's Customs, and marked the package as UNDELIVERABLE. Subsequently, even after I removed the restricted items and re-mailed the package, it was stpped by customs and returned to me. Next BAD experience was a woman clerk calling next, even though I was standing right at her counter; she stupidly tried to act as if I might have snuck up on her, until I wondered just how she though I (a disabled senior) might have snuck past 20 other people waiting in line. Next Bad experience: A woman postal clerk started to cover a package with required tape for REGISTERED mail, so I advised her that the rule only applied to DOMESTIC registered mail. She asked if I would like to try a different clerk? I told her of course not, but she was about to waste 5 minutes iof her time doing something that was not required on international parcels. Finally she went over to another clerk and fiund out I was right. Next bad experience was with the same Hispanic (Mexican?) supervisor I had the previous encounter with. This time he was supervising a new clerk, who did not have the answeres to my questions. Interjecting himself he ask ed me to step aside as there were CUSTOMERS waiting, to which I replied, "Suddenly I'm NOT a customer?" He then tried to answer every possible question he thought I might have, but he failed to answer the only question I actually had. When I suggested that it would be less expensive to mail two small flat-rate international packages with registered tracking ( $74) than the $61 it would cost to mail a medium size flat rate carton with built-in tracking, he MIScorrected that amount to $65 as if HE was the official with THE knowledge instead of just a tiny clerk one-step up from living on the streets. PA-THET-ICK!
