Residential hotel and passenger bus

Just after evening in Cox's Bazar way back in 1994, a rickshaw puller pointed out a restaurant, where people eat, saying that it is different from a hotel, where people stay, to a group of two, out on the streets looking for an eatery. In reports, the editors often come across an expression --- 'residential hotel.' One of the pet explanations the writers put forth is that the word 'residential' has been used to distinguish it from "hotels" were people dine. Hey, that is restaurant --- altogether a different word. Strange, they never write 'residential houses' or 'residential residences' as houses could also be used for commerical or recreational purpose.

Another such expression that is often found even in the local wire copies is 'passenger bus.' There are passenger trains and goods trains. But nobody has ever heard of any buses used solely for carrying goods. Buses always carry passengers and even when they carry goods, they are known as buses, and not goods buses. So there is no space for writers to distinguish buses, carrying people, as 'passenger buses.'
