Why don't people who are passionate about fish keeping work at aquarium shops?
Aside from the fact that we have to deal with the chronically daft people every day to a point it makes you want to just give up on the hobby?
Its not all fun and games working in aquatics, you have to sell, like it or not, customers *always* think they know better, its all about cleaning, cleaning, cleaning and serving customers, nothing glamorous like people seem to believe. And everyone knows that working in retail is never going to earn you much money... so essentially... your doing the job because you love it, right up until the point that customers destroy that love of fish and you leave
That said, if businesses aren't obligated to provide training, why would they then do so? Very few places provide training, I know
p@H do which is better than nothing... but barely... other than that... you might get a few small independants that pay to take the OATA course but few do, its expensive, not required and more benefit to the customer than it is the member of staff.
EDIT: And if a shop gives you transport bags for free, assume they are just being very generous. If a shop has to buy something, why should they be expected to give it to you for free? Its one thing if you have bought fish, they are hardly going to include a bag charge as well! But if you are just wanting bags without spending money in the shop...
