While travelling on Boeing B787 without much turbulence, a glass of wine slid off from the table, twice causing great embarrassment.
On the contrary, Boeing B767's table has a beverage hole to prevent such accidents from happening. It also has an extra sticker to clearly indicate the location of USB power outlet.
Combining features of Boeing B767's table (a beverage hole and a USB sticker) and the extendability feature of Boeing B787's table forms the ultimate table for a passenger airplane, as seen in another Boeing B767's table.
