Microwave installation needed a special installer for tile which was not explained to me at purchase. The second installer did a fine job but had to wait for his boss to get the ok since the cost of doing the work was in question. This delayed installation a couple of days and 45 min. for second installer to get the ok form his boss who contracts with HD. Not all people at the store to lack some training or basic knowledge which is kept to a few. More education for the people on the floor would help.
