The store tries painfully hard to create this hip "Abraxas" brand, and you have to sit there looking at an electronic billboard that was created by some 20 something marketing intern. Their website password is "iloveabraxas" which gives you an idea of how much they try to create customer loyalty.
So, that part is just annoying, but where they truly veer off course is in how they treat people. If you close for eyes for 10 seconds like I did (just to relax and listen to the music), they will accuse you of "sleeping" and some dim wit bouncer will trundle over and kick you out in the most pathetic passive aggressive way possible.
There are so many better options in A'dam. Don't waste your time...
