Here's a free business tip for you: If you tell your customers you open at 8am on Saturdays, then you should have someone there to open the store at 8am.
I waited until 8:11 this morning, when I absolutely could not wait any longer, and since you close before I'm off work and are closed on Sundays I'll have to wait until Monday-thank you for the huge inconvenience. I'll be certain to not inconvenience you with my business anymore.
