Is a girl's telling a beauty salon owner that she is an escort and not engaged, in order to avoid paying a higher amount for the same service, considered a deception or not?

It is permissible to request decorations for escorts from the salon owner without declaring that you are engaged or an escort, as this is not considered deception or fraud. However, claiming that you are an escort to an engaged woman when you are not is a prohibited lie and deception, due to the Prophet's (peace be upon him) saying: "Whoever cheats is not of me," and "Whoever cheats us is not of us, and scheming and deception are in the Hellfire."
