Quotation from: The Efficiency Expert

Written by: Edgar Rice Burroughs

Jimmy prided himself upon self-control, and his serving at Feinheimer's
had still further schooled him in the repression of any outward
indication of his emotions. For, as most men of his class, he had a
well-defined conception of what constituted a perfect waiter, one of the
requisites being utter indifference to any of the affairs of his patrons
outside of those things which actually pertained to his duties as a
servitor; but in this instance Jimmy realized that he had come very
close to revealing the astonishment which he felt on seeing this girl in
Feinheimer's and unescorted.
