I / we are very lucky to have such great mailmen/ delivery drivers. They are worth their weight in gold.As a business, I can only assume your package level is way beyond ours plus being in a metro area. It has to suck because you can't meet the commitment to your customers and they don't understand.
hardest working delivery driver??? FedEx has this one smaller girl driver. She works her butt off. Outpaces the guys by miles. I told her that if she ever needed a job to ask us first.
When I had my FFL and did the group buy on the gp100 revolvers. The shipper put something like 12 in one flat rate box and maybe a little newspaper around each. By the time they arrived at the office there were barrels poking out of the sides in more then one place. Mailman made sure I got the box in my hands (not that there would of been an issue but he didn’t know that)
Longest delivery.... when I was young (pre-teen) my family took a vacation to Mexico. While there I mailed my granny a postcard and forgot about it... years later (like 4-5) I get a call from her thanking me for it and why we didn’t let her know we were going out of town. It was that card from years earlier. She gave it back to me and I still have the card.
