"Really, I dodn't see why robbers always insist on doing thing's the hard way," she said to herself. "I'll have to ask Ryoko that someday. Maybe she'll be able to help."
Mentally adding that to her list of things to do; Washu built a gateway to the shopping center. "I really don't see what's so great about cars and all. So inefficient."
"Mmmmmm, senior discount; 10% off for anyone over eighty," Washu noted. "Well better hurry up and get my stuff. I wouldn't want Mihoshi to sneak into my lab unsupervised again."
Two hours later..............
"Crude, but I suppose it will work," Washu pushed a huge cart in front of her. "Now let's see. If this discount is cumulative then I'll get a discount of..........uh, lets see. Divide eighty into my age then multiply that by ten. I should get a 2500% discount!"
"Uh, hello," the store clerc said. "Are you waiting for your mom, little girl?"
"No, actually; I need this stuff for my lab. You see, the house I live at isn't a warehouse by any standard, and I need to get home before my roomate starts to loot my stuff."
"Uh, okay," the clerc started to ring up the items. "That would be $5,000. (Or the Japanese equizalent.)"
"I'm sorry," Washu smiled. "I think you did the math wrong. With the discount, it would end up being -$125000."
"But that would make you........" the clerc punched in some formulas on his calculator. "Almost twenty thousand years old. That's impossible."
"Oh so you don't believe me, do you?" Washu smiled again. "Lucky for me I brought my portable lie detector test. If I lie, I should get shocked by a whole lot of volts of electricity. Let's test it, my name is Bob," a small explosion happened, ending with Washu being covered with a thin line of ash. "Now, I'm twenty thousand years old." Nothing happened.
"Uh, okay," the clerc said dumbly. "Here's your $125,000."
