I had a customer who slow walked me on payment. So, I meet him at his house, took one of my roofers and put him on the roof with a bundle of shingles and a hammer, rang the door bell and homeowner started with I can't pay bullshit, so on que, roofer took some shingle tabs and started banging on the roof and tossing tabs off. Homeowner freaked. I told him that roofer would continue tearing off the roof if he wouldn't pay up. So, we got in my truck, took him to the bank and surprisingly he had the money to pay. Roofer was pissed I left him on the roof, but it all ended well.
