Cement and tar together? Is he trying to say asphalt but maybe couldn't spell that either? LOL That would be stone, not sement, I don't think sement and tar get used together.
Funny, we have a similar situation with a bar in a strip plaza, they complain about us doing the sidewalks and the "mess" we make (icemelt), so I made them sign a paper saying they would handle their own section of sidewalk, suits me fine--less shovelling and less material, same cost.
They also have regular customers and their staff that get drunk nightly, and while I commend them for not driving home afterwards I really wish they would all park together somewhere out of the way!!! Instead I have to deal with a half-dozen overnight parked cars (same ones over and over, including a work truck with ladders on a rack that stick waaaaaay out into the driveway threatening my windshield and mirrors every night) scattered throughout the (really small, tight) parking lot.
Thankfully, the owners of the plaza are really happy with our work (this is our 7th year with them) and even the new property managers they hired for the first time this year are happy too. In fact, theres a post-it note right in front of me that came with the last check from them that simply states "Thanks for the good service." and signed by the manager.
Was accused once of plowing in the garbage dumpsters at a gas station/store/subway I used to plow. Property manager called me in a tizzy, of course, I was dumbfounded. Told her I'd go there and get back to her. LEFT my dayjob in St. Catharines (told boss and he let me go but had to make up the time) went home to Niagara on the Lake, swapped car for plow truck and headed to jobsite (Niagara Falls). Got there to check the garbage... there was a 4" deep trail, 4" wide (cant get any closer than that!!) in front of the fence doors surrounding the bins. Seems the store staff had been too lazy to shovel that along with the sidewalks like they are supposed to. And the garbage truck guy was too lazy just kick it out of the way or just pull the door open... or tell the staff inside to bring a shovel. Someone calls the property manager, who called me.
Needless to say I was back on the phone with her basically (but professionally) ripped her a new one. Told her my job was not only done, it was done correctly, and this was store staff that had screwed up, and even still wasn't enough to stop the garbage guy other than for his own laziness. Why hadn't the manager gone to have a look if there was a complaint from the garbage man? Told her this how much effort and time it took to go there for nothing, and that it was her 'freebie', next time I got an unfounded complaint like that they would be charged for my wasted time.
They were a constant problem property. Dropped them after one season.
