Hi all, looking for some advice/perspective here.

I live in a city/region where hair salons have been closed since November 2020. They reopen tomorrow and I have an appointment on Friday.
Here’s my dilemma: I have a gift certificate to cover my services that also expires at the end of July. However, I’m feeling guilty about using it as that means no (new) revenue for my appointment.

Wondering if I should:
A) Use it but leave an extra large tip
B) Ask them if they are willing to extend the expiry date until my next appointment and just pay for my services on Friday
C) Decide to forgo the certificate altogether and never use it

If it makes a difference, the stylist who I’m seeing is also one of the salon owners.
