Not at all. I don’t offer tastings, I feel bad about it but I just can’t afford it. I will usually tell people the best I can do on that front is to offer them a discount on a small cake or cupcakes. This gives me a chance to showcase my talent as well as show that my work tastes good so they will have more faith. It’s worked for me so far!
Good luck to you, hope your potential client understands!
