I do not have a humidor, or any plans to buy one for this one time thing.

So i hear this Cigar shop in town has a very strict/snobby people who run it. My brother ( age 20 ) who delivered a county newspaper to the store said when he dropped off a stack of newspaper inside there shop when a when one of the store owners sons gave a statement of ” you have to be 50 years or older to come in here ” Keep in mind its a tobacco shop with a variety of cigars. Im wondering if i should walk in there ( im 18 ) because i really need a hygrometer for my cigar humidor. should i risk walking in there or no. And any tips how to make these people feel like im a cigar customer ?
sorry for grammar and typos
well not just one but about 7 reviews to the store with people criticizing saying yhey are snobby some say they are nice so i do not know how to deal with this situation i mean i am a customer lol
what if the owner gives the right to refuse service ?

For example, Romeo Y Julietta, Monte Cristo, some dark, some light, etc, etc.
