I am in the commercial real estate business and it is very common for sellers to make up all kinds of stories to cover up the fact that they are selling their business, such as saying that only the building is for sale or they are just getting new financing or a million other excuses. The main reason is the rumors that get started and people coming into the property and asking questions...then the employees start to panic about their future employer and pretty soon the employees all quit and go to work somewhere else. Then they are short handed and selling a business without the experienced staff you once had. I always suggest the business owner should sit down with the employees and be honest with them and explain what is going on, even offering them a bonus to stay on and help the new owner.
IMHO, the bottom line is it doesn't matter which one is for sale...things change, sometime for the worse, sometimes for the better. Maybe the new owner, of whatever shop it happens to be, will provide a better service or offer something the old owner was reluctant to attempt...such as banked mixed gasses or different product lines, or maybe better operating hours. I just think it's a shame the guy getting divorced has to deal with increased stress over all the rumors that must be floating around the shop.
