specific tournament tipping question

[edingerlaw 0]

Recently, I played in a local Indian casino NL tournament. The buy in was $120.00. We got 5000 in chips. Everybody was basically forced to pay an additional $5.00 for 500 additional chips. This $5.00 was to go totally to the dealers. There were 22 tables with 10 at each table. 99% bought the additional $5 so basically every dealer got $50.00 in tips out of this.What is an appropriate tip to leave if you won or got in the top 3? Some of the top finishers made 2,000 to 4000 and only left 50 to 100 bucks in tips. (deals were made) And the dealers were ungrateful. In light of the $5.00 tax already, I believe $50 to 100 is more than enough for a$2,000 to $4,000 win. What do you think?
