I have come to realize where my son in law is concerned I always select the prefect gift if I get him something for his bar. He loves to entertain and you just cannot go wrong if people are the type to have barbeques and parties tobuy drink coasters.
I have always found it harder to buy gifts for men than finding the right gift for a woman. However if they are entertainers it does make the choice of gift easier. You can get gifts that will be of service and even have coasters custom made and personalized.
I use drink coasters around the house instead of saucers, They are easy to just wipe clean and leave in place to protect the furniture from marking. I even use them in the caravan. I don't like drink glass or coffee cup marks on furniture.
