Well that escalated quickly.
I wouldn't apply one persons opinion to the overall personality of the forum. We've got different creeds, genders and preference. As such the forum is a melting pot of unique individuals.To each their own.
As an admin of the site I find myself having to be diplomatic and neutral but I will add in my two cents here. While I don't see any harm in asking for samples, after all the worst case is they'll say no, I do find harm in judging a supplier simply because they don't send samples. Flat rate shipping costs about $5.50 add in the wholesale cost of liquid (cost varies) over a few hundred requests and you find yourself spending out quite a bit of capital. For larger companies, sure, this is probably a drop in the water, but for smaller companies that extra cost my better be used for additional items, new products etc.
So while you're out asking for samples, don't judge a company or put them don't simply because it's not something they offer. Especially if no prior purchase has been made. (For example we don't ship out free samples on the fly, but we will usually honor sample requests to those asking in an order note. That way the sample is sent along with their already existing order. It keeps our costs down while still allowing our customers to try something new. It's a win win in my opinion)
