The other thing to consider is that over time, or as we get older, or more experienced hobbyists or whatever - our expectations of service level change.
There was definitely a time where I was more than willing to walk into a store and get caught up in the fun hype surrounding an event or a new release. I didn't necessarily buy anything at that time, but being involved in thtat kind of positive atmosphere can be great at times.
These days, my expectations have changed. I am the kind of shopper that 9 times out of ten (or likely more) I will know exactly what I am after and will know more about the product than the staff themselves. I'm a pretty friendly guy generally speaking - but even I can see how that would be a difficult case for a staff member to work with unless they just disengage and let me go for it - which ultimately makes it harder for them to hit their store targets.
It's quite understandable really. But there truly are some shockers out there.
One thing I will say though - GW's training standards are still the best hands down that I have come across in any retail chain to date. There's a good reason why I picked up the required skills to make a career out of vocational education & training.
