Note that there are no spaces on either side of the ampersand in such instances.
Often, we use an ampersand for names of companies, such as Menon @ Menon and Mills & Boons.
Most of the students nowadays use the ampersand in forma writings very often and haphazardly:
Richard & Mary came yesterday.
The cart was loaded & sent away.
This is a ‘spill over’ influence from ‘Texting’ and should be avoided.
We should always spell out the word and in these cases.
