What does TCB mean in Aretha franklins song respect?

Taking Care of Business

Crealkiller Says: the lyrics on a website i found says its this:

Chorus:

R-E-S-P-E-C-T

Find out what it means to me

R-E-S-P-E-C-T

Take care, TCB

so i doubt TCB is taking care of business

it wouldn't make sense to take care, taking care of business
