My guess is that the Ace Ticket sales reps on the phone get a commission, and that Ace Ticket purposely doesn't include the seat numbers online so that you have an incentive to wait until they're open and call the sales rep on the phone.
What is 'Collective Bargaining'. Collective bargaining is the process of negotiating the terms of employment between an employer and a group of workers.
Plea bargaining is a significant part of the criminal justice system in the United States; the vast majority (roughly 90%) of criminal cases in the United States are settled by plea bargain rather than by a jury trial. Plea bargains are subject to the approval of the court, and different States and jurisdictions have different rules.
