I must suggest to hubby to get the "No Parking" sign to be placed on the entrance door. Some of the customers who cycled to the cyber cafe love to park their bicycles right in the middle of the entrance. Fine, I know you want the shade but park at the side not blocking other people's way into the shop.
Besides "No Parking" hubby need to get a bigger safety signs; "No Smoking" to be placed inside and outside of the toilet. If possible arh, those that come with water sprinkler once it detects smoke. Got sign also no point for those stubborn customer; water sprinkler is best for this kind of people!
