This for sure. About 2 years ago, we hadda do a medical facility and it had about 350 ADA signs. When I got the specs, I asked if they met ADA requirements and they verbally told me yes. In my bid, I put a line item in, which stated, we were only doing the installation part of the job. If things need to be changed out for whatever reason, we would not be held responsible for removal or re-installing new signs.... again for whatever reason. They had signed off, probably not even paying attention to that statement. Got the job done and needless to say, the signs were gorgeous, but after the inspection a few weeks later, they were notified that the colors did not match their initial proofs submitted about a year earlier. They asked me to fix it. I sent them a new quote for removing all the signs and hanging all the new ones. I felt bad for them and gave them I think, a 15% discount. They practically bit my head off, telling me I was wrong for charging like this. I should be this and should be that...... and I just said to the guy.... do you remember my telling you these signs didn't look like they'd pass an inspection ?? That's why I put that line item in. I know the area and told you to be sure. This time, I requested my money upfront. They b!tched about that, too. I didn't care. Didn't need the hassles or headaches. About 2 weeks later or so, received the check in it's entirety and scheduled the work the day after the new signs came in. Dumb sh!ts though made the new signs exactly the size of the old ones telling me they'd fit the old templates. Yeah, right. About 2/3s of them fit, but you try drilling out 400 holes and drilling them over an 1/8" or 3/16" over. Luckily it happened on one of the first ones we did. Figured out how to oval out the hole and just force the screws in. Screws were ever-so-slightly skewed, but it worked and everyone was happy in the end. Never heard back from that company.
