When it comes to contractors I use my frown and moustache as part of my negotiating. It doesn't work though but after the barbeque was built it was all smiles. This wasn't a small job that involved a 60 year old bbq taken apart while reclaiming a lot of the brick then move it closer to the patio. My patio area I ended up replacing the ratty old wood with travertine stone tiles.
The fellas were friendly and the job was done past any expectations.
