I’m going to see Violet Fire, an opera about Nikola Tesla at BAM, tomorrow. My friend Kristen is an understudy. After purchasing a ticket, the confirmation page displayed the following: “We are currently unable to deliver email receipts.” I’m not generally a critic of commerce web sites since they are actually really difficult to implement. But this is fairly lame. The BAM web site requires your email address–in fact, that is how you log in. It is really, really easy to send simple email. I have no idea why they cannot send an email receipt.
