Motorola wined and dined customers in the Innovation Center, usually with tours of the museum. Sometimes it was a buffet style lunch but at some meetings they actually had table service with wait staff and menus.
They also gave a lot of souvenirs. My favorite was the leather bound notebook. I snagged as many as I could as often as I could and used them for years. Eventually coworkers "borrowed" them or they disappeared from my office until now, 30 years later, I have only two left. I did notice one on my Chief's desk but I didn't say anything as I was up for a promotion at the time.
They also had other items emblazoned with the "Big M" or the company name. These included polos, t-shirts and, if you were really lucky or a potential big customer, a windbreaker. I had several shirts and a windbreaker but they all seemed to have shrunk a few sizes over the years so ended up at the SA store. They also freely gave out Post-Its and little cheap tool kits and other bling at trade shows and customer meetings.
